Monitoring Microsoft clustered servers requires some extra configuration. This how-to describe how to configure OP5 Monitor to monitor drives and win32-services on clustered Windows servers.
Drives/partitions
Since Drives/partitions in Windows server clusters can failover between the physical servers, the drives need to be checked/monitored via the virtual server names.
First, you need to add the virtual servers as new hosts in your configuration.
Second, add services to these new hosts. See example below:
| service_description: | Disk usage Q: |
| check_command: | check_nt_disk |
| check_command_args: | Q!88%!95% |
Services
In a Windows server cluster, the Win32-services are named using the format 'win-servicename$virtualhostname'. To monitor these services, the $-sign needs to be escaped in check_command_args. See example below:
| service_description: | SQL Server service |
| check_command: | check_nt_service |
| check_command_args: | MSSQLSERVER\$$virtualhost |
