Custom chart for JVM Busy Threads

[martin_gradev]

Hello,

As part of our monitoring solution, we need to add a Custom chart showing the JVM Busy Threads and also define an alert in case it reach some threshold.

Is this possible with the current version? I can recall that before 2 months (maybe more) I was able to configure such chart. What was changed?

BR,

Martin

Hi,

right now we have the following metrics for JVMs:

• GC invocations
• GC time
• Memory (committed)
• Memory (used)
• Thread count

I am not aware of any change in this area.

@Thorsten R. - I am sure I was able to add JVM Thread busy before. Is there a way to tweak something in the configuration in order to enable this metric?

[martin_gradev]

Are we going to bury this thread or I can expect a meaningful update?

[thorsten_roth]

As I told you, I am not aware of any metric like this.

I was able to create such chart from Title catalog -> Infrastructure -> Process group. Select process group type: Java, Select metric: Threads - Busy threads. It is not very functional, e.g. on click you are redirected to a random host instead of having a chart, but at least it provides some insights for our whole environment.

Interesting and good to know. It seems that the metrics differs from what we have in the custom charting.

[martin_gradev]

Yes, it is not a custom chart and that's the problem with the functionality, as these metrics are not sorted in a table (like all custom charts), but you are redirected to the metrics for a specific host. Maybe a future improvement?

Absolutely, I will forward this to the right person. Appreciate it.
