How to Monitoring AIX cluster

[rcremasco]

We need to monitor an AIX cluster.

We installed the zabbix agent on both node, all check on the single node are working fine.

Then we configured a new host for the virtual IP for the clustered resourse. Now the item created un that node is giving the error:

Get value from agent failed: ZBX_TCP_READ() failed: [4] Interrupted system call



How we can monitor the clustered resources?

thanks

On my AIX clusters, I run an agent on each node, which is listening to the server on port 10050

This is defined in /etc/zabbix/zabbix_agentd.conf

You need to make sure you update the following:

Logfile=/tmp/NODE_logfile.log
PidFile=/tmp/NODE_logfile.log
Hostname=NODE
ListenPort=10050

This agent is started at system boot on both nodes.

I then tell the zabbix server about each node and apply the Template_AIX

I then run *another* zabbix agent, which is started by hacmp which runs the same zabbix_agentd daemon, but uses different config file.

-rw-r--r-- 1 root system 8738 Jul 12 15:01 zabbix_agentd_cluster.conf

In here, I change the following:

PidFile=/tmp/zabbix_agentd_cluster.pid
LogFile=/tmp/zabbix_agentd_cluster.log
HostnameItem=system.hostname

NOTE: the reason why I use "HostnameItem=system.hostname" as opposed to "Hostname" is because when a cluster failover occurs, the hostname of the active node is changed by the hacmp failover scripts (which are executed by the "hostname MY_CLUSTER" and "uname -S MY_CLUSTER" commands).
FWIW - assuming your service label is "MY_CLUSTER", this also means that I can run scripts independent of hacmp which start off with :

if [ `hostname` != "CLUSTER" ]
then
exit 0
fi


anyhoo.....back to the "zabbix_agentd_cluster.conf"...
In here, I also change the port which the MY_CLUSTER version of the agent will listen on, to a different port than the one being used by the NODE.

ListenPort=11050

I then create a *new* host (i.e. "MY_CLUSTER") on the zabbix server, and point it at port 11050

I then configure the create a template host called "Template_MY_CLUSTER" and apply it to the host called "MY_CLUSTER"
( Typically, these are the things that are in the cluster resource group, such as application availability, and storage that's been created for the application).

Finally, with reference to: https://www.zabbix.com/forum/showthread.php?t=41224
I then create an zabbix(agent) item in a template called "Template_PowerHA" and apply it to each node in the cluster.

You need to add the following *single line* in the /etc/zabbix/zabbix_agentd*.conf" (or wherever you put your zabbix agent config file(s))

# START #

UserParameter=Cluster_State,CLUSTER_STATE=`/usr/bin/lssrc -ls clstrmgrES | grep "^Current state" | awk ' { print $NF } '` ; if [ "$CLUSTER_STATE" = "" ] ; then echo 0 ; elif [ "$CLUSTER_STATE" = "ST_NOT_CONFIGURED" ] ; then echo 1 ; elif [ "$CLUSTER_STATE" = "ST_INIT" ] ; then echo 2 ; elif [ "$CLUSTER_STATE" = "ST_STABLE" ] ; then echo 3 ; elif [ "$CLUSTER_STATE" = "ST_JOINING" ] ; then echo 4 ; elif [ "$CLUSTER_STATE" = "ST_VOTING" ] ; then echo 5 ; elif [ "$CLUSTER_STATE" = "ST_BARRIER" ] ; then echo 6 ; elif [ "$CLUSTER_STATE" = "ST_CBARRIER" ] ; then echo 7 ; elif [ "$CLUSTER_STATE" = "ST_RP_RUNNING" ] ; then echo 8 ; elif [ "$CLUSTER_STATE" = "ST_RP_FAILED" ] ; then echo 9 ; fi

# END #


Hope this helps, but drop me a line if you need any more info...

Thanks,

Template_PowerHA

Here's the template I was talking about...

Hii guys,
I am new in Zabbix Monitoring.
Right now I already use zabbix for monitoring my Windows Hyper-V Cluster.
I already use dafyre idea, install zabbix agent on Server 1 and 2, I also input the Cluster-Name on Zabbix-Host Monitoring.
but i have issue with the Quorum Disk, when the Quorum on Server 1, Server 2 Triggres have alert "The trigger is not discovered anymore and will be deleted in xxDay xxHour xxMinutes"

Is it there is idea the best practice for Monitoring Hyper-V Cluster in Zabbix Monitoring??
thanks Before
