Cluster Management of Nimsoft Probes

The Cluster probe enables fail-over support for a set of Nimsoft probes in clustered environments. Probe configuration that has been associated with a Resource Group will follow that group to the Cluster Node that the group running on. The probe will also send alarms if a Resource Group or Cluster Node changes state.

The data collection is implemented as plugins. How the plugins collect data from the cluster differ, but the information returned by the plugin is always the same.
The collected data must contain the name and state of the Nodes, the name and state of each Resource Group and on what Node they are running. This information is used to manage where the different probe configurations should run and not run.

Supported Clusters

Microsoft Cluster Service (MSCS)
The plugin has been verified on Microsoft Cluster Service version 5. This plugin collects data using the Cluster Server API found in the Windows SDK.

Veritas Cluster Service (VCS)
This plugin collects data from the cluster using the command hastatus -summary.

Note: The Nimsoft cluster probe supports all Microsoft Cluster configurations.

Important: Profile name(s) of Nimsoft probe profiles that are to be "clustered", needs unique names across the cluster.

Supported probes:

  • Exchange_monitor (Only supported on MSCS) ( Active/Active, Active/Passive and N+I node cluster)
    (supported in cluster probe version 1.61 and newer)
  • CDM (disk profiles only), (Active/Passive and N+I node cluster) (supported in cluster probe version 2.20 and newer)
  • Processes (2-node Active/Passive. N+I node clusters as long as profile names are unique)
  • NTServices (2-node Active/Passive. N+I node clusters as long as profile names are unique)
  • Logmon (2-node Active/Passive. N+I node clusters as long as profile names are unique)
  • Dirscan (2-node Active/Passive. N+I node clusters as long as profile names are unique)
  • SqlServer
  • Oracle
  • Ntperf


Notes:

  • Version 2.2x: Changed behaviour when running with cdm probe version 4.0x.
    The cdm probe will receive information about cluster disk resources from the cluster probe and create monitoring profiles for these based on the 'fixed_default' settings. These profile are automatically registered with the cluster probe to ensure continous monitoring on cluster group failover. In the cdm probe, the cluster group is used as Alarm and Quality of Service source instead of the cluster node.
    Note that on upgrade old monitoring profiles in the cdm probe for the cluster disks are overriden with the new ones.
  • Cluster probe 2.51 and above do not support CDM probe below version 4.20. All the sub mounted and cluster disks in the CDM probe needs to be manually reconfigured when upgraded to 4.20 or above.


Installation notes

All the cluster nodes must run a Robot with a identical set of probes installed.
Revision history
Date Description State Version
02.07.2021

What's New:

  • Added support for RHEL 8.x (x86_64).
  • Added support for Microsoft Visual C++ Redistributable for Visual Studio 2017 package version 1.01 (vs2017_vcredist_x86 1.01 and vs2017_vcredist_x64 1.01). This support ensures that the minimum version of the VS 2017 package is equal to or greater than 1.01.

Fixed Defects:

  • Unable to select MS Cluster Shared Volume in cluster probe. Support case number: 31924995, 31931481
  • Cluster probe causing sqlserver profiles to disappear. Support case number: 01358985
  • Cluster failover leaves passive node in unexpected state. Support case number: 32389063
  • CDM Probe Error -[9784] cdm: Unable to register section /cluster/XXXXXX/disk for group XXXXX with cluster probe (error). Support case number: 32327697

GA 3.71
02.03.2020

What's New:

  • Alarm source drop down has been added to accommodate all the 3 possible values of alarm source which are "Node IP" (default one), "Cluster Name" and "Robot Name". 
  • Added ‘auto_configure_profiles' key in the raw configuration of the cluster probe to support automatic profile creation.

Fixed Defect:

  • The Cluster probe reads wrong file system names in the Veritas cluster. Salesforce case number: 01132664

3.70
20.07.2018

What's New:

  • Added support for Redhat Pacemaker Cluster monitoring.

Note: The Redhat Pacemaker Cluster behaves differently from other supported clusters. If a resource group’s state is Down, these groups are not displayed on the probe GUI, although the alarms and QoS are sent by the node to which the group belongs (last owner).
