hi
how to monitor IP SLA on NPM for Cisco 819 ISR ?
Npm doesn't natively do ip sla monitoring. They have a module for that called vnqm, https://documentation.solarwinds.com/en/success_center/vnqm/content/vnqm_getting_started_guide.htm
If you get fancy you could do some form of sla monitoring in just npm by building a custom UNDP aimed at the relevant oids. solarwindscore.my.site.com/.../Create-a-Universal-Device-Poller-UnDP
I don't have the details to hand right now, but I did just this as Marc suggests using OIDs and a UnDP.
