In an older post I described the steps to integrate check_openmanage Nagios plugin with check_mk. This approach required manually editing the etc/check_mk/main.mk file to configure the extra_nagios_conf and legacy_checks.
This updated guide uses the check_mk WATO (Web Administration Tool) to integrate the check_openmanage check using a feature called "Active Checks".
Here's the guide, hope it helps:
Environment:
- CentOS 6.5 x86_64 VMware ESXi hosted virtual machine
- OMD 1.10
- check_openmanage 3.7.11
- Check_mk 1.2.5i4 upgraded using these steps
- Dell servers are checked via check_openmanage using SNMP rather than MRPE (or NRPE)
Install Check_openmanage
Unless otherwise specified all paths are relative to the site owners home (ex: /opt/omd/sites/mysite)- Make sure your dell servers had the following SNMP packages installed prior to installing OMSA (if not, it's easy to 'yum remove srvadmin-\*' 'yum install srvadmin-all': net-snmp, net-snmp-libs, net-snmp-utils
- Start the OMSA services 'srvadmin-services.sh start' and then check 'srvadmin-services.sh status' to verify that the snmpd component is running
- Ensure that snmpd is running and configured
- Configure the firewall to allow access from your OMD server to udp port 161
- Start the OMSA services 'srvadmin-services.sh start' and then check 'srvadmin-services.sh status' to verify that the snmpd component is running
- change users on your OMD server to the site user: $ su - mysite
- Download the latest check_openmanage from http://folk.uio.no/trondham/software/check_openmanage.html to ~/tmp and extract
- copy the check_openmanage script to local/lib/nagios/plugins (this defaults to $USER2$ in your commands)
$ cp tmp/check_openmanage-3.7.11/check_openmanage local/lib/nagios/plugins/ $ chmod +x local/lib/nagios/plugins/check_openmanage - copy the PNP4Nagios template
$ cp tmp/check_openmanage-3.7.11/check_openmanage.php etc/pnp4nagios/templates/ - Test check_openmanage to see that it can successfully query a node

WATO Configuration
- Create a Host Group by clicking Host Groups under WATO - Configuration, click New Group (click save when done):
- Name: omsa
- Alias: Dell OpenManage
- Create a Host Tag by clicking Host Tags under WATO - Configuration, click New Tag Group (click save when done):
- Internal ID: dellomsa
- Topic: (leave empty)
- Choices:
- Tag ID: omsa
- Description: Dell OpenManage
- Create a Active Check by clicking Host & Service Parameter under WATO - Configuration, click Active Checks, click Classical active and passive Nagios checks (create a new one, click save when done):
- Folder: Main Directory
- Host Tags: Select Dell OpenManage is set
- Service Description: check_openmanage
- Commmand Line: $USER2$/check_openmanage -H $HOSTADDRESS$ -p -C MySecretCommunity
- Service Description: check_openmanage
- Check Perfomance Data
- Add the omsa Host Tag to a host running OpenManage with SNMP configured by clicking Hosts under WATO - Configuration, and click the properties editor (pencil icon) for the host (click Save & go to Services when done):
- Host tags: Dell OpenManage: check Dell OpenManage twice
On the Host services page you should see the new service at the bottom, example:
Custom checks (defined via rule) Status Checkplugin Item Service Description Plugin output OK custom check_openmanage check_openmanage OK - System: 'PowerEdge R710', SN: 'XXXXXX1', 24 GB ram (6 dimms), 2 logical drives, 14 physical drivesClick Activate Missing services or Save manual check configuration. Activate the changes and you should start seeing the check within a few minutes and graphs after 10 minutes or so. Hope this helps, and comments are welcome.
