Nagios monitors dell server hardware We have mentioned earlier that omsa is used to monitor dell servers, but it must be accessed through web. This time we use nagios + check_openmanage to monitor the hardware of dell servers. First, let's look at the figure below: We can see that there are two ways to achieve monitoring: 1. The nagios server check_nrpe calls the check_openmanage of the monitored server. This method requires omsa and check_openmanage
