OP-26831 - Hotfix release for customers using Opsview Monitor 6.0 Early Adopter with Opsview Agent 5.x monitoring hosts on RedHat/Centos 7.

SYMPTOMS

In an environment using Opsview Monitor 6.0 Early Adopter with Opsview Agent 5.x monitoring hosts on RedHat/Centos 7, service and host checks states may appear to be stale, due to the NRPE potentially returning binary data that cannot be parsed. The syslog throws an error such as [ERR] Dumping unparsable message.

ROOT CAUSE

RHEL7 no longer provides the lsb_release by default.
Only environments where the lsb_release is not installed are affected.
When running, the Opsview Agent declares a variable to which the output from the lsb_relase would be written. However, if the lsb_release command is not available this variable is not initialized, therefore returning binary data to the service check output. At term, the service/host check state is marked as stale. The results of the check are therefore unusable.

RESOLUTION

The delivered fix provides a solution for Opsview 6.0 Early Adopter to handle binary data.
Please follow the steps below to update your servers (Master and Collectors) with the fix.

  1. Download and install the package
    For Debian/Ubuntu
    sudo apt-get update
    sudo apt-get install opsview-executor
    For RHEL/CentOS
    sudo yum install opsview-executor

  2. Start the Executor component:
    sudo /opt/opsview/watchdog/bin/opsview-monit start opsview-executor

NOTE

There is no issue when running Opsview Monitor 6.0 Early Adopter with Opsview Agent 6.
