How can I parse a remote command (ssh) and create elements.

[greg35]

Hi Everyone,

I need to check a network device (Cisco), by ssh, and parse some results to create some items.
I don't know how can I do that.
My goal : to monitor peering BGP by VRF (up or down). The exisiting template it's not enough for my needs. So, I must check by ssh (sh bgp vrf all summary) and parse differents peers.
Have you an idea ? I checked the documentation but I didn't find

Thanks a lot

The item of type "SSH agent" will return textual data by default, but you can use preprocessing rules to extract the specific data you are looking for. Or, you can use "show bgp vrf all summary" output as a master item and then create several dependent items for parsing different BGP sessions.

For BGP session monitoring, however, I personally would investigate using an HTTPS API or even SNMP to query the BGP session information, instead of using the (slow) SSH connections.

Hi Markku,
Thanks, I'll try 'use "show bgp vrf all summary" output as a master item and then create several dependent items for parsing different BGP sessions'
We can't use SNMP because we need to create "contexts" snmp and we haven't rights to do that, just read right on devices.
Stay tuned !

So, I have to parse "my text" by JavaScript, and return somes values ${IP} -> ${STATUS}, to create several depends items ?
I 'll try.

No, it doesn't works... I would like create dynamically dependent items by peering VRF but with JavaScript parsing, I have return just one value, so I don't know how can I do my needs

https://www.zabbix.com/documentation...y/custom_rules has some examples of LLD JSON output that gives you idea how to format the discovery rule output.

Thanks Markku, it's a success !
I can now parse (with pre processing JavaScript) my command result and create some elements (via an item prototype).
Thanks !
