Prometheus/Zookeeper version

[My Me]

Hi all,

We are using Prometheus 2.3.1.  Prometheus internally uses zookeeper.

Have couple of questions:

1) How to find out the version of "zookeeper" being used in Prometheus 2.3.1 ?

2) How to find which version of Prometheus uses "zookeeper" version 3.4.10 or later ?

Thanks in advance,

Best Regards,

Kanthi Kumar

Hi Martin,

Are you saying that Prometheus doesn't use Zookeeper internally ?

I could see this in one of my container running Prometheus 2.3.1: (refer attachment).

Prometheus itself doesn't use Zookeeper, however it can talk to an external Zookeeper to discover targets.

I guess you are both right, somehow. :)

Prometheus does not require Zookeeper and it's not a core feature.
However, Prometheus can use Zookeeper for its service discovery. It
therefore contains a zookeeper client library.

The following file might help as a pointer which version is used:

Kind regards,
