check_snmp_synology - General Linux Plugin?

[chris1337c]

I have tried the check_snmp_synology plugin extensively, disabling different aspects of it, it continuously times out (after 180s). I thought I had found the issue with the NIC bonding on the box itself but it started timing out again. I have updated the owner of this plugin and see I am not alone.

My question is, can anyone recommend a general linux plugin that can be used to effectively monitor network connectivity and general health of the box? Or does it have to be specific to manufacturer?

Is there a template I could use to plugin specific MiB's to just make one with the features I need?

Open to any and all suggestions, of our 50+ hosts Nagios functions 100%, except for this synology box.

I do synology monitoring using its own monitoring (health check).

In addition you could - depending on the services you have enabled for it - check if it is responding on the service specific ports. I.E. Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server.

If you mount if somewhere you could check for existence of the mount point using /proc/mount in a script if you are on linux. And using check_disk plugin you could monitor its available disk size by using specific filter/s if it is mounted, see https://www.monitoring-plugins.org/doc/ ... _disk.html

Hello, @chris1337c. We do have the check_snmp plugin that allows you to pull info on a custom OID. It is not limited to the manufacturer.

The problem with the generic check_snmp plugin is that sometimes it returns non-formatted data that is hard to understand. Custom plugins on the exchange, on the other hand, were designed to convert that data into a human-readable format. That's why I suggest looking for an alternative plugin on the exchange first and if nothing works then use the generic one.

Hi.
It seems to me like there is a patch available for the plugin. See William Yangs post from january, 30th.
