NetXMS Support Forum

Hello,

I would like to monitor shared disk and service resources in a Windows 2003 Active/Passive cluster.  The only information I've found on it is in a post at https://www.netxms.org/forum/index.php/topic,391.msg1915.html#msg1915, but I'm unable to translate it correctly.

How would I setup monitoring to for disk space on a cluster, as well as services such as exchange or ms-sql?

Thanks in advance.

Hello!

Here are translation of mentioned post, should be enough to setup shared resource monitoring.

It's an example of cluster monitoring configuration.

Case:
We have two cluster nodes: NODE_A and NODE_B. Cluster itself is called CLUSTER. Both nodes have NetXMS agents installed. Nodes are connected to public network 192.168.1.0/24, node A has address 192.168.1.11, node B - 192.168.1.12. Also, both nodes has private network 10.0.0.0/8, node A has address 10.0.0.1, node B - 10.0.0.2. There are 3 resource groups:
1. Cluster group, name: ClusterGroup, virtual IP 192.168.1.10
2. Shared disk, name SharedDisk, virtual IP 192.168.1.20. On active node seen as drive X:
3. Exchange server group, name: Exchange, virtual IP 192.168.1.30. On active node run Exchange services and drive E: contains shared Exchange data.


Requirement:
Monitoring service availability and disk space.


Configuration steps:

1. Create object of type "Cluster", call it CLUSTER (it is no necessary to match AD cluster object name)
2. In CLUSTER object properties add cluster interconnect network 10.0.0.0/8
3. In CLUSTER object properties on "Resources" page define resources (name - IP pairs):
    ClusterGroup 192.168.1.10
    SharedDisk 192.168.1.20
    Exchange 192.168.1.30
4. Now we can create nodes A and B. They should be created under CLUSTER object. As Ip addresses for new nodes should be used their fixed IP addressesd (192.168.1.11 and 192.168.1.12 in our example).
5. Check configuration of new nodes - virtual addresses of cluster resources should not appear as interfaces. If you select CLUSTER object in object browser, on "Cluster" page should be displayed correct position and status of cluster resources.
6. Now DCIs for cluster resources can be defined. Select "Data Collection" for CLUSTER object, and create DCIs as usual, except one: you should select correct cluster resource in "Associate with cluster resource" field. Fo example, for monitoring disk space on shared disk X:, you should set "Associate with cluster resource" to "SharedDisk" in our example. DCIs configured that way will be collected only from node which is current owner of associated resource.
7. All other configuration for cluster nodes can be done as usual.


There are also some predefined events related to cluster monitoring:

SYS_CLUSTER_DOWN
SYS_CLUSTER_UP
SYS_CLUSTER_RESOURCE_DOWN
SYS_CLUSTER_RESOURCE_UP
SYS_CLUSTER_RESOURCE_MOVED

You can process them as usual in event processing policy.

Best regards,
Victor
