Discovery / Service Mapping error: All command implementations (SNMP_TABLE) failed on host [IP Address]. Host might be down or unreachable.

Hi team,

I've got the following error on one of our service maps; All command implementations (SNMP_TABLE) failed on host 192.168.254.53. Host might be down or unreachable.

The map was correctly populated and complete. I hit Run Discovery to get the latest data. Once done, all components disappeared and I was left with the entry point and load balancer. The application team confirmed there was no change to the entry point or load balancer of this service and yet I am no longer able to map its component. Could you please help with what needs to be done to resolve this error:All command implementations (SNMP_TABLE) failed on host 192.168.254.53. Host might be down or unreachable.

thanks. I've looked at this. The challenge is that the class Citrix Netscaler is already on the sys_choice table and we've already got an SNMP mapping discovery command where Citrix Netscaler is on Operating System Class Name list. So even with that, I still get the same error! Any ideas?

Hi,

How you where doing service mapping? Traffic based or tag based.

Thanks,

Hi, it's pattern-based discovery. I've started to notice this issue now happening on other load balancers (that used to show up perfectly fine on the map, but now have this error)
