Considerations and workarounds

New download site

Beginning on 1 December, 2017, downloads for Resource Manager customers are available on delivery.zenoss.com only. Leapfile is no longer used.

Compatibility with Zenoss Service Impact

This version of Resource Manager is compatible with Zenoss Service Impact version 5.2.2 or later.

Excessive zeneventd memory usage

An issue with self-monitoring causes excessive memory usage on the zeneventd service. To work around the issue, configure crontab of the root user on the Control Center master host to restart zeneventd every midnight. For example, to sudo crontab -l add the following entry:
0 0 * * * /usr/bin/serviced service restart zeneventd >/dev/null 2>&1

Layer2 ZenPack

The Layer2 ZenPack (ZenPacks.zenoss.Layer2) is resource intensive. If you do not intend to use it, Zenoss recommends uninstalling it.

NFS client 4.1 is not supported

A file locking defect might exist in NFS 4.1 with RHEL/CentOS 7.4, which could cause zeneventserver to crash and other DFS-related problems. For more information, refer to topic "Configuring NFS 4.0" in the Control Center installation guide or upgrade guide, or knowledge base article Potential Issues Running With RHEL 7.4 Or CentOS 7.4.

CentralQuery maximum memory allocation pool

(ZEN-15907) The size of the CentralQuery maximum memory allocation pool is set by the RAMCommitment variable in the CentralQuery service definition. The default value is 1024MB. Do not change the value to anything less than 1024MB.

Upgrade considerations

  • (ZEN-29337) When Nutanix ZenPack (ZenPacks.zenoss.Nutanix) version 1.0.1 is installed, a known problem with management of ZenPack dependencies during upgrade will cause the upgrade to fail. This problem will be addressed in the next maintenance release of Resource Manager. Zenoss advises customers who are using the Nutanix ZenPack version 1.0.1 to wait for the new release.
  • Do not attempt to upgrade systems on which DEV ZenPacks have been installed; the upgrade will fail. This limitation will be addressed in an upcoming release of Resource Manager. In the meantime, to upgrade, uninstall DEV ZenPacks, perform the upgrade, and then reinstall the DEV ZenPacks.
  • (ZEN-29103) No data is collected for the ZenossRM device after an upgrade if the localhost collector is moved off the master host. If you have moved the localhost collector off the Control Center master host, you must set the following properties for the ZenossRM device to enable data collection.
    1. Navigate to the ZenossRM device overview page and select Configuration Properties.
    2. Set the following zProperties:
      • zRMMonCCHost - Enter the IP address of the Control Center master host.
      • zRMMonCCUser - Enter the name of the ccuser account, which is the default account for gaining access to the Control Center browser interface.
      • zRMMonCCPassword - Enter the password of the ccuser account.
