From 5.4.x to 6.3

Learn how to do an in-place upgrade from Opsview Monitor 5.4.2 to Opsview Monitor 6.3


This document describes the steps required to upgrade an existing Opsview Monitor 5.4.2 system running on either a single server instance or a distributed Opsview environment (with a remote database and slaves) to the current version of Opsview Monitor.

Depending on the size and complexity of your current Opsview Monitor system, this process may take between a few hours to a full day.


You must be running a minimum of Opsview Monitor 5.4.x to perform an in-place upgrade If you do not have version 5.4.2x then you must either upgrade to that first or perform a migration to new hardware instead.


If you are running Opsview Monitor in a virtual environment then you should snapshot the servers before the upgrade is started. You then have the option to 'Roll Back', should any problems occur.

If you are not using a virtual environment, then you may wish to perform a migration to new hardware instead of an in-place upgrade.


The in-place upgrade process is made up of the following stages:

  • Setup of local repo (offline only)
  • Bootstrap Opsview Deploy
  • Preparing to upgrade
    • Gather information about the Opsview 5.4 environment.
    • Manually fine-tune the opsview-deploy configuration.
  • Performing the upgrade (this will include OS updates unless otherwise overridden, documented below)
  • Registering Opsview collectors


Before upgrading from Opsview Monitor 5.4 to Opsview Monitor 6.3, make sure that you have...

  • A supported operating system.
    If you are running Ubuntu 14.04 or earlier then upgrade the OS before upgrading Opsview by following these steps OS and Opsview Upgrades.
  • Shell access (as 'root') to the Opsview Master server.
  • SSH access from the Opsview Master server (as root user) to itself.
  • SSH access from the Opsview Master server (as root user) to all Opsview Slaves.
    • This must use key-based authentication - password authentication is not supported.
    • The target user (on the Opsview Slaves) must either be 'root' user or have full, password-less 'sudo' access including the ability to elevate to the 'root' user.
  • Root access to the MySQL server(s) from the Opsview Master server.
    • The MySQL username must be 'root'.
    • The root user must have access using mysql_native_password (installation using the auth_socket plugin to access the database is not currently supported).
  • Offline upgrades - Setting up the mirror is outside of this documentation, but we suggest using a tool to achieve this such as reposync for CentOS and RHEL, or apt-mirror for Debian and Ubuntu.

The base URLs for mirroring our repositories are:


# Ubuntu/Debian


  • Any remote Opsview databases must listen on 3306/TCP for inbound connections.
  • External 'opsview-timeseries*' hosts are not automatically added to the inventory.
  • Local 'opsview-agent' configuration must be manually reapplied when the upgrade process is complete.
  • Using NAT'd IP addresses to communicate from the Opsview Master to the Opsview Slaves has not currently been tested.
  • Advanced Apache configurations cannot be converted and adopted automatically.
  • The deployment must be executed from the Opsview Master.
  • 'opsview-timeseries' nodes which are not using the RRD backend must be manually upgraded as the InfluxDB backend is not yet supported by opsview-deploy.
  • If you are using opsview-sshtunnels for communications to some or all collectors, check SSH Tunnels page to ensure you have the correct configuration set up

Performing the Upgrade

Disable Previous Opsview Monitor Repositories


Disable older Opsview repos!

You must comment out or remove any previous Opsview Monitor repository configuration for yum or apt.
Opsview Monitor 6.x uses a slightly different repository to versions 4 and 5. If references to either remain, older packages may be incorrectly installed or referenced.

/etc/yum.repos.d/opsview.repo (CentOS/RHEL) or
/etc/apt/sources.list.d/opsview.list (Debian/Ubuntu)
and place a # character at the start of each line. If these files do not exist, check other files in the same directory for references to

Refresh the repositories:-

yum clean all
yum makecache fast

# Debian/Ubuntu
apt-get clean
apt-get update

Offline Only

You will also need to take a copy of the installation script (and verify its checksum) before transferring this to the target server:

curl -sLo- > install_opsview
sha256sum install_opsview

Ensure the returned string matches the following:


Bootstrap Opsview Deploy (Online)

To configure the latest Opsview Monitor repositories and install opsview-deploy, run:

curl -sLo- | sudo bash -s -- -A boot

Bootstrap Opsview Deploy (Offline Only)

Using the Opsview Monitor deploy script loaded earlier, install the initial package set. Specify the Opsview Monitor admin <password>.

bash ./install_opsview -p <password> -O fire,boot

Gather information about Opsview Monitor 5.4 environment

As root user, cd to the '/opt/opsview/deploy' directory and execute the 'upgrade-pre' playbook.

root@opsview-master:~# cd /opt/opsview/deploy
root@opsview-master:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/upgrade-pre.yml

This will create a directory at '/opt/opsview/deploy/var/upgrade/' with a symlink at '/opt/opsview/deploy/var/upgrade/latest'.

This directory will get populated with various files to be copied or parsed during the upgrade. These include:

  • /usr/local/nagios/etc/opsview.conf
  • /usr/local/nagios/etc/sw.key
  • /usr/local/opsview-web/opsview_web_local.yml
  • /opt/opsview/timeseriesrrd/etc/timeseriesrrd.yaml (original version)
  • Process maps
  • Custom Host Icons
  • Custom Host Template icons

Finally, the 'opsview-deploy' configuration will be produced:

  • /opt/opsview/deploy/etc/opsview_deploy.yml
  • /opt/opsview/deploy/etc/user_secrets.yml
  • /opt/opsview/deploy/etc/user_upgrade_vars.yml
  • /opt/opsview/deploy/etc/user_upgrade_vars_tmp.yml

The file 'user_upgrade_vars_tmp.yml' will be removed once the upgrade is complete.

Fine-tune the opsview-deploy configuration

Once the initial 'opsview-deploy' configuration is created, it may need to be tweaked to suit the installation environment as outlined below.

Before continuing, make sure that you review 'user_upgrade_vars.yml' configuration; it will contain extra information with additional steps you may need to follow.

You should merge the settings from user_upgrade_vars.yml into user_secrets.yml and user_vars.yml once the upgrade is complete. Before proceeding with the upgrade, make sure these three files do not have any conflicts with each other. If you find a conflicting setting, merge the setting you want to keep into user_vars.yml (for configuration) or user_secrets.yml (for passwords).

Configuring Opsview Collector Clusters

If the Opsview 5.4 environment had slaves configured, these will have been added to 'opsview_deploy.yml' in the 'collector_clusters' section. Any inactive nodes will be commented out for convenience.

Each node needs to be updated with the correct SSH user. Additional variables (e.g. SSH port) can be configured as per the below:

        ip: <IP_ADDR>
        user: <SSH_USER>
        port: <SSH_PORT>


A note on YML File Spacing

The yml configuration files are sensitive to spacing.
Do not use 'tabs', use individual spaces and ensure that the alignment is retained.

Configuring the root password for the Opsview database

The MySQL root password must be added to 'user_secrets.yml':

# /opt/opsview/deploy/etc/user_secrets.yml
opsview_database_root_password: MyPassword

The password must be the 'root' user's password for the database server hosting the 'opsview' and 'runtime' databases.

If you do not do this then you may receive the below error when attempting an "Apply Changes" within the UI later:

"ERROR 500: (1142, "DROP command denied to user 'opsview'@'localhost' for table 'nagios_contacts_temp'")
Failed to generate configuration"

If you don't have root access to the database server, see the notes in 'user_upgrade_vars.yml' for the steps you need to follow.

Configuring the database hosts

You may notice this option in your 'opsview_deploy.yml':

database_hosts: {}

You MUST leave this option as-is. Your database hosts are configured in 'user_upgrade_vars.yml' instead (otherwise, 'opsview-deploy' might reinstall your database server!). See the notes in 'user_upgrade_vars.yml' for more info.

SNMP Trap Processing

This is a licensed feature. To have the SNMP trap Processing software upgraded, add to /opt/opsview/deploy/etc/user_upgrade_vars.yml:

opsview_module_snmp_traps: True 
Configuring common overrides and parameters

Any additional options can be added to 'user_vars.yml'. For example:

# /opt/opsview/deploy/etc/user_vars.yml
# Install and manage a local Postfix MTA on each node
opsview_manage_mta: yes

# Relay host for outgoing mail

# Disable automatic updating of the OS packages (not recommended) .
opsview_manage_os_updates: False

# Force installation of the named module instead of only installing if enabled by the license
opsview_module_netaudit: True
opsview_module_netflow: True
opsview_module_servicedesk_connector: True
opsview_module_reporting: True
opsview_module_snmp_traps: True

Offline Only
Amend the file /opt/opsview/deploy/etc/user_vars.yml and add in the following appropriate line for your OS to specify the URL to your local Opsview Monitor package repository mirror:

opsview_repository_str_yum: 'http://my.repo/$basearch/'
# Debian/Ubuntu
opsview_repository_str_apt: 'deb http://my.repo/ trusty main'

check_uri_opsview_repository: "http://my.repo/"

Pre-Deployment Checks

Before running opsview-deploy, we recommend Opsview users to check the following list of items:

Manual Checks

All YAML files follow correct YAML formatopsview_deploy.yml, user_*.ymlEach YAML file is parsed each time opsview-deploy runs
All hostnames are FQDNsopsview_deploy.ymlIf Opsview Deploy can't detect the host's domain, the fallback domain 'opsview.local' will be used instead
SSH user and SSH port have been set on each hostopsview_deploy.ymlIf these aren't specified, the default SSH client configuration will be used instead
Any host-specific vars are applied in the host's "vars" in opsview_deploy.ymlopsview_deploy.yml, user_*.ymlConfiguration in user_*.yml is applied to all hosts
An IP address has been set on each hostopsview_deploy.ymlIf no IP address is specified, the deployment host will try to resolve each host every time
All necessary ports are allowed on local and remote firewallsAll hostsOpsview requires various ports for inter-process communication. See: Ports
If you have rehominguser_upgrade_vars.ymlDeploy now configures rehoming automatically. See Rehoming
If you have Ignore IP in Authentication Cookie enableduser_upgrade_vars.ymlIgnore IP in Authentication Cookie is now controlled in Deploy. See Rehoming
Webserver HTTP/HTTPS preference declareduser_vars.ymlIn Opsview 6, HTTPS is enabled by default, to enforce HTTP-only then you need to set opsview_webserver_use_ssl: False. See opsview-web-app

For example:

  # Use an FQDN here
    # Ensure that an IP address is specified
    # Set the remote user for SSH (if not default of 'root')
    user: cloud-user
    # Set the remote port for SSH (if not default of port 22)
    port: 9022
    # Additional host-specific vars
      # Path to SSH private key
      ansible_ssh_private_key_file: /path/to/ssh/private/key

Automated Checks

Opsview Deploy can also look for (and fix some) issues automatically. Before executing 'setup-hosts.yml' or 'setup-everything.yml', run:

root:~# cd /opt/opsview/deploy
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/check-deploy.yml

If any potential issues are detected, a "REQUIRED ACTION RECAP" will be added to the output when the play finishes.

The automatic checks look for:

CheckNotes or LimitationsSeverity
Deprecated variablesChecks for: opsview_domain, opsview_manage_etc_hostsMEDIUM
Connectivity to EMS serverNo automatic detection of EMS URL in opsview.conf overridesHIGH
Connectivity to Opsview repositoryNo automatic detection of overridden repository URL(s)HIGH
Connectivity between remote hostsOnly includes LoadBalancer ports. Erlang distribution ports, for example, are not checkedMEDIUM
FIPS crypto enabledChecks value of /proc/sys/crypto/fips_enabledHIGH
SELinux enabledSELinux will be set to permissive mode later on in the process by setup-hosts.yml, if necessaryLOW
Unexpected umaskChecks umask in /bin/bash for 'root' and 'nobody' users. Expects either 0022 or 0002LOW
Unexpected STDOUT starting shellsChecks for any data on STDOUT when running /bin/bash -lLOW
Availability of SUDOChecks whether Ansible can escalate permissions (using sudo)HIGH

When a check is failed, an 'Action' is generated. Each of these actions is formatted and displayed when the play finishes and, at the end of the output, sorted by their severity.

The severity levels are:

HIGHWill certainly prevent Opsview from installing or operating correctly
MEDIUMMay prevent Opsview from installing or operating correctly
LOWUnlikely to cause issues but may contain useful information

By default, the check_deploy role will fail if any actions are generated MEDIUM or HIGH severity. To modify this behaviour, set the following in user_vars.yml:

# Actions at this severity or higher will result in a failure at the end of the role.
check_action_fail_severity: MEDIUM

The following example shows the 2 MEDIUM severity issues generated after executing check-deploy playbook

REQUIRED ACTION RECAP **************************************************************************************************************************************************************************************************************************
[MEDIUM -> my-host] Deprecated variable: opsview_domain
  | To set the host's domain, configure an FQDN in opsview_deploy.yml.
  | For example:
  | >>
  | >>    ip:
  | Alternatively, you can set the domain globally by adding opsview_host_domain to your user_*.yml:
  | >>  opsview_host_domain:
[MEDIUM -> my-host] Deprecated variable: opsview_manage_etc_hosts
  | To configure /etc/hosts, add opsview_host_update_etc_hosts to your user_*.yml:
  | >>  opsview_host_update_etc_hosts: true
  | The options are:
  | - true   Add all hosts to /etc/hosts
  | - auto   Add any hosts which cannot be resolved to /etc/hosts
  | - false  Do not update /etc/hosts

Initiating the upgrade


The following steps will make changes to your Opsview environment. Ensure that you've taken adequate backups before continuing.

If you have Reporting Module installed then now is the time to shut it down so that packages upgrade successfully:

root:~# /etc/init.d/opsview-reporting-module stop

To upgrade the Opsview environment, run the following playbooks in the '/opt/opsview/deploy' directory:

You will receive either a SUCCESS or FAILURE message, if you receive a SUCCESS, proceed, but if you receive a FAILURE please investigate and resolve this before moving forward.
You will be required to re-run the same steps in order to see if the error/failure has been resolved

root:~# cd /opt/opsview/deploy
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/setup-everything.yml
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/upgrade-post.yml

Upgrade Opspacks

Run the following as the opsview user:

root:/opt/opsview/deploy# su - opsview
opsview:/opt/opsview$ /opt/opsview/coreutils/bin/install_all_opspacks -f -d /opt/opsview/monitoringscripts/opspacks

This may take a moment to run.

Syncing all Plugins to Collectors

This step will copy all updated plugins on the Master to each of the Collectors and should be run as the root user:

#  This will...
#        Distribute plugins from Master to Collectors by running the following playbook
root:~# cd /opt/opsview/deploy
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/sync_monitoringscripts.yml

Webserver SSL Certificate

In Opsview 6 we now provide a new location to drop in SSL Certificates for use in encrypting traffic between the users and the Web UI. Because the location of the SSL certificates previously in use by Opsview 5 is not determined by the upgrade, you must manually drop the certificate and key into the new location. The new location for the certificate and key is /opt/opsview/webapp/etc/ssl/ while the old location was /usr/local/opsview-web/etc/ssl/.

As root, move your SSL certificates into the correct location while backing up the generated self signed ones:
Note: these steps assume the default location for server certificates, your location may be different, so change /usr/local/opsview-web/etc/ssl/server.crt and /usr/local/opsview-web/etc/ssl/server.key accordingly.

cd /opt/opsview/webapp/etc/ssl/
mv server.crt{,_selfsigned}
mv server.key{,_selfsigned}
mv /usr/local/opsview-web/etc/ssl/server.crt ./server.crt
mv /usr/local/opsview-web/etc/ssl/server.key ./server.key
/opt/opsview/watchdog/bin/opsview-monit restart opsview-webserver

If you have other SSL configuration such as the use of intermediate CA certificates or the use of .pem files then please see opsview-web-app for more information

Registering the Opsview Collectors

If you were using Opsview Slaves, these will now be Opsview Collectors and they need to be added to their respective clusters in the UI.

  • Navigate to: 'Configuration' -> 'Monitoring Collectors'.
  • Select each of the 'Unregistered Collectors' pane and choose 'Register Collector'
  • Select the collector cluster to associate this collector with
    • This must be the same cluster as per the 'opsview_deploy.yml' configuration

Running the initial Apply Changes (formerly known as Reload)

In order to get all the new components up and running correctly, an Apply Changes must be completed

  • Go to 'Configuration' > 'Apply Changes' to finalise all the changes made by the upgrade process.

Moving the Database Server

If you wish to move your database to an infrastructure server, refer to Moving database.

Moving to the InfluxDB Graphing Engine

If you wish to move from the RRD graphing engine to InfluxDB, refer to Timeseries Graphing Engine.

If you are already using InfluxDB then you do not need to take any further steps.

Opsview 5.X Host Templates deprecation

The following host templates are no longer relevant for Opsview 6.x, so you need to manually remove them from the Opsview Orchestrator and Collectors; you can safely delete the Templates and their Service Checks:

  • Application - Opsview BSM
  • Application - Opsview Common
  • Application - Opsview Master (succeeded by the Host Template "Application - Opsview" with it's own new service checks, you can add this template now)
  • Application - Opsview NetFlow Common (succeeded by the Host Template "Opsview - Component - Results Flow")
  • Application - Opsview NetFlow Master

Reporting Email Configuration

As part of the upgrade to this Opsview Monitor release, the JasperReports Server part of the Reporting Module has been upgraded from 5.1.1 to 7.1.1. With this upgrade, the file will be replaced, overwriting any contents in it. This file is used to configure the emailing capabilities of the Reporting Module and will need reconfiguring if it was previously configured.

To edit this file, open /opt/opsview/jasper/apache-tomcat/webapps/jasperserver/WEB-INF/ in a text editor and edit the default "report.scheduler.mail.sender." values to match your requirements. See Reports - optional module for more details.

Double Proxying and Rehoming

Please note that with the introduction of websockets in 6.2 there must be an additional ProxyPass section in the proxy configuration if you are using Apache2 or NGINX for a forward or reverse proxy. See Rehoming

NRPE overrides in nrpe_local

Custom NRPE plugins and configuration overrides are not migrated by the upgrade - these changes should be performed manually.

As the root user on the Orchestrator and Collector servers, copy the configuration files from the old location to the new one:

cp  /usr/local/nagios/etc/nrpe_local/*.cfg /opt/opsview/agent/etc/nrpe_local/
chown root:opsview /opt/opsview/agent/etc/nrpe_local/*.cfg
chmod 640 /opt/opsview/agent/etc/nrpe_local/*.cfg

The paths to plugins will also need to be updated within the configuration files, which can be easily done with the following command:

sed -i 's!/usr/local/nagios/libexec!/opt/opsview/agent/plugins!'  /opt/opsview/agent/etc/nrpe_local/*.cfg

All of the plugins configured within the cfg files should be copied over, too (the example below is for a custom plugin called

cp /usr/local/nagios/libexec/ /opt/opsview/agent/plugins/
chown root:opsview /opt/opsview/agent/plugins/

After all plugin have been copied over, restart the agent and make sure the nrpe process is running as the opsview user:

service opsview-agent restart
ps -ef|grep nrpe

You can test a custom plugin called check_exec for running the following, which should produce the help output for the plugin:

sudo -iu opsview /opt/opsview/monitoringscripts/plugins/check_nrpe -H localhost -c check_exec -a '-h'

You may also need to amend the custom plugins to ensure they do not use old obsolete paths.

/tmp files owned by Nagios

Some plugins may create temporary files within commonly used directories such as with /tmp and running the plugins as the opsview user may show permissions problems resulting in non-OK states or error messages within the UI.

This can usually be resolved by running the following command on the Orchestrator and Collector servers:

chown -R --from=nagios:nagios opsview:opsview /tmp/* /var/tmp/*
