Embeded Event Management widely used?

[ahmad82pkn]

Hi, i need to ask is EEM Applets are recommended to use and regularly used in networks?

Like i used it once and experience was bad that, my Router kept crashing as soon event generated, so i never worked on it since then.

But now i have some requirement where i have no other option to use that on Cisco ASR, and that router is critical.

So my questions is, do you guys use it ? :)

is it widely used?

is it recommended?

is it stable config ?

If anyone has any good use case scenarios article that would be great.  ( Found few on internet, but wanted to check some extensive examples to unleash the features )

thanx all.

I use it on maybe 1 in 200 routers that I configure.  I only use it when I can't find a way of getting the router do wherever it is automatically.

I've always found it to be stable and worked well.

Don't have any issue with it either , you just need to be careful building them and how long you leave them run for especially if there collecting data , I use them a lot for collecting cpu issues there very handy for that as you need to get the statistics in real time

There is some good examples in this link
