From 6.3 to 6.4

Learn how to do an in-place upgrade from Opsview Monitor 6.3 to Opsview Monitor 6.4


This document describes the steps required to upgrade an existing Opsview Monitor 6.3 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.

Summary of process

  • Back-up your Opsview data
  • Upgrade Opsview Deploy and Opsview Python
  • Run deployment process
  • Verify processes started
  • Upgrade Opspacks
  • Apply changes in Opsview Monitor



Upgrade process

Minor upgrades


Minor upgrade information

When performing any upgrade it is advisable to take a backup of your system and therefore this is why the minor upgrade steps mirror that of the main upgrade steps

Activation Key

Ensure you have your activation key for your system - contact Opsview Support if you have any issues.

Backup your Opsview data/system

Please refer to Common Tasks for more information.

Run the below command as root which will back up all database on the server:

# mysqldump -u root -p --add-drop-database --extended-insert --opt --all-databases | gzip -c > /tmp/databases.sql.gz

The MySQL root user password may be found in /opt/opsview/deploy/etc/user_secrets.yml.

Ensure you copy your database dump (/tmp/databases.sql.gz in the above command) to a safe place.

Opsview Deploy

Upgrading to a new version of Opsview Monitor requires the following steps:

  • Add the package repository for the new version of Opsview Monitor
  • Install the latest Opsview Deploy (opsview-deploy) package
  • Install the latest Opsview Python (opsview-python) package
  • Re-run the installation playbooks to upgrade to the new version

Once the upgrade has completed, all hosts managed by Opsview Deploy will have been upgraded to the latest version of Opsview Monitor.

Upgrading: Automated

#  This will...
#   * Configure the Opsview Monitor 6.4 package repository
#   * Upgrade opsview-deploy to the corresponding version
curl -sLo- | sudo bash -s -- --only repository,bootstrap
#  This will execute opsview-deploy to validate and upgrade Opsview
root:~# cd /opt/opsview/deploy
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/check-deploy.yml
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/setup-everything.yml

Once completed, continue with the Post-upgrade Process

Upgrading: Manual

Amend your Opsview repository configuration to point to the 6.4 release rather than 6.0, 6.1, 6.2 or 6.3


Check the contents of /etc/yum.repos.d/opsview.repo matches the following, paying special attention to the version number specified within the baseurl line:

name    = Opsview Monitor
baseurl =$releasever/$basearch
enabled = yes
gpgkey  =

Check the contents of /etc/apt/sources.list.d/opsview.list matches the following, paying special attention to the version number specified within the url. NOTE: replace 'xenial' with your OS name (as per other files within the same directory).

deb xenial main

Update Opsview Deploy

yum makecache fast
yum install opsview-deploy
apt-get update
apt-get install opsview-deploy

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 (opsview_deploy.yml):

  # Use an FQDN here
    # Ensure that an IP address is specified
    # Set the remote user for SSH (if not default of 'root')
    ssh_user: cloud-user
    # Set the remote port for SSH (if not default of port 22)
    ssh_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

Run Opsview Deploy

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

Post-upgrade process

As part of the upgrade process, Opsview Deploy overwrites the contents of the configuration files for snmpd and snmptrapd. If Deploy detects that the file itโ€™s overwriting had changes made to it, the configuration file will be backed up and labelled with a timestamp while the new configuration replaces it.

REQUIRED ACTION RECAP *************************************************************************

[MEDIUM -> opsview-orch] SNMP configuration file '/etc/snmp/snmpd.conf' has been overwritten
  | The SNMP configuration file '/etc/snmp/snmpd.conf', has been overwritten by Opsview Deploy.
  | The original contents of the file have been backed up and can be found in
  | '/etc/snmp/[email protected]:31:32~'
  | Custom snmpd/snmptrapd configuration should be moved to the custom
  | configuration directories documented in the new file.

A message like this appearing at the end of a run of Opsview Deploy indicates that the configuration file in the message has been overwritten. To avoid this in future, all custom snmpd and snmptrapd configuration should instead be put in new xxxx.conf files in the following directories respectively:

  • /etc/snmp/snmpd.conf.d
  • /etc/snmp/snmptrapd.conf.d

Run Post-upgrade tasks

#  This will execute setup-monitoring to perform post-upgrade tasks
root:~# cd /opt/opsview/deploy
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/setup-monitoring.yml

Verify processes started

To verify that all Opsview processes are running, run:

/opt/opsview/watchdog/bin/opsview-monit summary

If the opsview-agent process is not running after deployment, run:

/etc/init.d/opsview-agent stop
/etc/init.d/opsview-agent start
/opt/opsview/watchdog/bin/opsview-monit start opsview-agent

If watchdog is not running after deployment run:


Upgrade Opspacks

Run the following as the "opsview" user:

tar -zcvf /var/tmp/`date +%F-%R`_opspack.bak.tar.gz /opt/opsview/monitoringscripts/opspacks/*
/opt/opsview/coreutils/bin/import_all_opspacks -f

This may take a moment to run.

Syncing all Plugins to Collectors

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

#  This will distribute plugins from Master to Collectors
root:~# cd /opt/opsview/deploy
root:/opt/opsview/deploy# ./bin/opsview-deploy lib/playbooks/sync_monitoringscripts.yml

Apply Changes in Opsview

In the Opsview application UI, navigate to "Configuration" - "Apply Changes", and run "Apply Changes".

Uninstall Python 2 binaries


Before Uninstalling Python 2 Binaries

If you have written your own monitoring scripts, notification scripts or integrations using the Python 2 binaries provided by the opsview-python package instead of your own Python implementation, you might be impacted by Opsview Monitor Python 3 migration. We recommend to migrate your own monitoring scripts, notification scripts or integrations to use the Python 3 binaries provided by opsview-python3 package or your own Python implementation.

To uninstall the Python 2 binaries provided by the opsview-python package from your Opsview Monitor system after upgrading to 6.4, please run the following command as root on your Opsview deployment host (where opsview-deploy is installed; often the master host)

root:~# cd /opt/opsview/deploy && bin/opsview-deploy lib/playbooks/python2-uninstall.yml
