Hello everyone,
I have configured an Alert in NPM for Node Down, which means if any of the network devices in our production setup goes down and remains down for 15 minutes, an Alert will be generated. Furthermore, I have integrated this Alert with our ticketing portal, so when any network device goes down an email alert will be generated and also a ticket will be created and will be automatically assigned to the local On Site personnel. In our current network setup, we have Internet routers as well as MPLS routers which are managed by third party and behind the Internet and the MPLS devices we have our switches, voice gateways etc. Sometimes I observer that there's a power outage at a particular site where the Internet router and the MPLS router both go down and subsequently, all the switches which are behind the Internet and MPLS device, also go down and this creates tickets where where we see all devices are down and when we follow up with local IT people, they inform us that there was a power outage.
When both the Internet and MPLS devices go down, it's obvious that there's a power outage due to which all the associated switches also go down. I wanted to eliminate at least this case where MPLS and Internet devices both go down at the same time, we obviously know that there's a power outage.
So is there a rule which we can create which states that, if Internet device as well as MPLS router both go down, then an alert shouldn't be created OR the alert should be suppressed as we know that there's a power issue?
I would appreciate some help on this.
