You can use a regular expression to do this, or you can use multiple associations.

It would be nice if our parser was smarter and understood more english-like syntax, but that is beyond my abilities at the moment :)

Thanks All!

I was able to set-up some alert checks. 

I am trying to implement the following use case.

On specific port channels of a switch, we would like to monitor the network traffic and expect Observium to alert whenever it sees a traffic of less than say 0.1%.

To achieve this I created the appropriate check on Observium. See attachment - "Alert"

How can I put multiple statements in the Entity field? I do not want these entities as AND but I want them as OR. For example "ifAlias match PC101" OR  "ifAlias match PC101"

If you mouse over the (i) icon on the alert list, you'll see what the last data seen by the alert checker was.

I was able to get the alert configured on one of my switches. 

But doesn't looks like it is working. The rule says send out an alert when the traffic percentage is more than 50 %  (In our case which should be more than 5 Gbps).

I ran a performance tool for 15 minutes giving me a throughput of ~9 Gbps on ethernet port 1 but I do not see any alerts in the alert check. See attachments.

Change your Device match to * and Entity match to *.

 

After that it working, work at narrowing your hostname and entity.

Thanks Kevin!

 

I did clicked the 'regenerate' button but does not see a match.

 

I wonder if my alert is set right, since it doesn't seems to have any match. I see everything as 0/0/0/0.

 

Steve, I tried changing the entity match to ifDescr not match Loopback*  but see the same thing.

Hi Renuka,

 

Here’s what mine looks like. Got 192 interfaces being monitored.

Hi All, 

 

I am just starting to use alert checker in Observium.

 

I started with a basic alert checker on one of my switches but not sure if it is working. See attachment.

 

I wanted Observium to set an alerts if the traffic on any of the ports exceeds 50%. 

 

I ran a network performance tool on one of my machine (sending traffic at 8-9 Gbps) but I don't see any alerts been generated. 

 

 

Thanks!

 

 

Regards

Renuka
