How nodejs cluster metrics are calculated in APPDYNAMICS?

CommunityUser — Mon, 22 Jan 2018 07:11:47 GMT

I'm using NODEJS cluster (1 master and 4 worker threads) totally 5 processes are running on my machine. But in the metric browser page, It is showing only single GC metrics?

what about others?

How cpu, GC, eventloop, memory metrics are all calculated for the nodejs cluster environment?

Is there any document available for this?

Hi Devraj,

Do you see 5 nodes in the Tiers and Node Tab in the application or just one node ?

Are you on SAAS, or ON-PREM ? If SAAS, please share the URL when the metric browser is open with this metric.

Thanks

Ayush

Yes I can able to see the 5 nodes in the Tiers page (I downed one.)

Are you on SAAS, or ON-PREM ?

I'm using SAAS

If SAAS, please share the URL when the metric browser is open with this metric.

Please find the attached image.

My question is where I can see the cpu usage for the 5 nodejs processes?

Hi Devaraj,

Please have a look at this link.

[Redacted]

There are Metrics of GC for each node, and the aggregate GC for all Node.Js in the link above.

The screenshot if the GC you showed earlier was from the aggregate one. You can drill down to individual nodes to view the specific GC and other details.

Please let us know if you have more queries.

Thanks

Ayush

Hi ,

I'm running totally 1 master and 4 worker threads but here it's showing only 4 processes.

Where is the master process?

But in tier page it showing 5 process, Is master process is skipped?
