Can we frequently visit monitor http server?

[wubumihuo]

we have met several production problems, so we want to get each connection detailed monitoring info such as connSubscriptions，pendingbytes. can we visit and update monitor http server for 1 time/sec?

Yes you can access /connz, or using the NATS api to get the same data from a system user.

If you have production issues, you might consider a commercial relationship with Synadia.

Also what server version?

[wubumihuo]

we use version 2.8.4； our connections is about 500

[derekcollison]

Wow.. Try installing the latest server which is 2.10.5.

But yes that should be ok, but would use the API vs HTTP.

[wubumihuo]

Thanks. We mainly use java-client, does API support java?

Most folks use the NATS cli, but anything that can be done in NATS cli you can add --trace to the end and it will show the request and the request subject and the reply of everything it is doing. NATS cli also has schemas which you can use to marshal and unmarshal JSON.
