Can you elaborate a bit on what kind of event/alert you want to raise ? from gNMIc to where? With which protocol ? ...
Thanks Karim for responding. Here is my use case 1) I have an observability frontend on all my network devices. 2) I use gnmic to subscribe to these multiple network devices (routers/switches.) to moniter their state and resport back to my front end using Kafka. So for instance if an interface goes down, i get an event through subscription event and i put it in a Kafka Topic which can be consumed by different software components to report the state to the front end user quickly. 3) However if the router itself goes down, I cannot directly figure that out using any events or triggers from gnmic, The only way i can see right now is through log files where gnmic reports broken connection. 4) So what i have to do is to run a script that reads the file continiously to see the relevant error and then put this as a message in Kafka Queue to communicate a router going down.Similarly when i see a log of connection getting re-established I send a message to communicate a router coming back online.
So my query is where my solution at point 4, is it the best i can do with Gnmic or is there a more streamlined approach offered(Through some trigger/event in gnmic itself)?
Thanks agin
To solve a similar issue we use a single subscription (device version) as a "heartbeat" which is run every minute. If our application detects that it has not received a message on that topic for >3min (3 intervals) we consider it to have gone offline and we increment a prometheus counter in our application. We then clear this prometheus counter if we see the device begin sending messages again.
Hi,
My issue is the capability to to raise an alert when a target goes down.
If i turn off a target router, i see an error logged in the log file and gnmic trying to reestablish connection. Is there a way an event/trigger of the same can be generated? Or should i just write my own script to scrap the log file for this event and raise an alert from the script?
Thank you
