Interface response times alerting

Hello all,

I am trying to figure out a way to collect information about an interface response times or packets loss to alert on. I will give you the situation so hopefully that helps out.

ISP 1 connects to breakout switch

breakout switch connects to firewall.

ISP 2 connects to breakout switch

breakout switch connects to firewall.

HCO is monitoring the firewall interfaces for both ISP's.

ISP 1 was having some issues with connectivity that we did not detect. Internet was steered to ISP 2 but there was no indication that ISP 1 was having issues since the physical connection never went down. The ISP 1 modem connected to the break out switch never went down so the interface was always up but the service was down. I could see that on the firewall itself. The response times and latency were through the roof when looking at the firewall management itself.

I opened a support case but they have come back and said that HCO doesn't monitor the interface itself rather the node so there is no metrics I can pull other than interface up or down to alert on. Since ISP 2 was fine the whole time I would think alerting on the node wouldn't help me. Support suggested that I post something here to see if the community has been able to accomplish this.

Thanks everyone.

I'm not fully understanding.

You say: "HCO is monitoring the firewall interfaces for both ISP's" and then you say support says: "HCO doesn't monitor the interface itself". Either I'm misreading or there is some confusion.

First. To monitor interfaces you need to monitor the node via SNMP. If that is true, then a 'list resources' should enumerate the interfaces On the presumption that the former is true, then all you should need to do is configure an alert to trigger on traffic util or something similar.

Stuartd,

I agree. You can get the stats by using SNMPv3 and ensuring interfaces and selected in "list resources".

Additionally, you can add widgets to the node page which will show delay, loss of packets, QOS ques, etc.Not all of those feature appear based on the node template you select when initially building/adding the node.

If you can confirm that you are polling the stats you want, you can use/turn on the standard cookie cutter Alerts and Reports to get the information desired. Worst case you can copy the Alerts and Reports, rename them, and refine them to report on only specific interfaces or devices.
