I've used Nagios in the past, but have not kept up with its development and |
| 27 |
the many plugins it provides. It could do any of the above tasks and much |
| 28 |
more. It can run scripts (perl, or bash) via daemons (nrpe) on the remote |
| 29 |
systems to restart applications, et al. The Nagios server possessed the |
| 30 |
ability to set up quite intelligent monitoring and alert hierarchies with |
| 31 |
multilayered comms structures to make sure you are not woken up at 2 a.m. by |
| 32 |
your boss, just because a ping failed to his home NAS. I also found the logs |
| 33 |
which can be also stored on SQL quite useful both in troubleshooting problems |
| 34 |
and in producing reports. It can monitor network connectivity, remote OS |
| 35 |
parameters and applications. Writing your own plugin/module to monitor quite |
| 36 |
specialised use cases is not particularly difficult either. |
| 37 |
|
| 38 |
I expect you may find Nagios more complicated to set up than monit, at least |
| 39 |
initially, but if you don't have the luxury of time to invest on setting up |
| 40 |
Nagios monit may be a better fit. I don't have in depth experience with other |
| 41 |
monitoring software to comment, so something else may suit better your |
| 42 |
specific needs. |
