Bottleneck Alert Probability 100% Annoying?


If you don't want to see the default (annoying!) Performance related alerts in HPOM, the ones similar to this...

Network Bottleneck Probability 100%

... then I hope you realise you can turn them off!

I saw one client who forget to do this, and due to the messages not being seen by any user profile or account, the quantity of these alerts was HUGE, and took a long time to get cleared-down manually, wasting time & effort.

I'll write more about these alerts in the future, and how they CAN be of use, but they need to be configured carefully and with planning, thought and care, as they are not intuitive or helpful out-of-the-box.

Here's how you check the current status of the performance agent:

/opt/perf/bin/agsysdb –l

And this is the command to turn off the sending of performance alerts to HPOM:

/opt/perf/bin/agsysdb –ovo off

Bear in mind that agent upgrades can turn this feature back on, so you might want to ensure your procedures include steps to turn it off again if required.

Alternatively, you could create a monitor to alert you if it gets enabled!  Now there's a thought...
