Hi,
I am trying to find the units for the following zookeeper metrics, can some
one please share?
zk_avg_latency ---> s,ms,us ?
zk_max_latency ---> s,ms,us ?
zk_min_latency ---> s,ms,us ?
zk_approximate_data_size --->bits,bytes,kb,mb ..etc?

Hi,
We have a multi data-center zk cluster with all the followers are in one
data-center and observers in other data-centers, for some reason observers
are going down with the following exception and i am not sure what could be
the reason and how to avoid this issue, any thoughts?

Hi,
We have a zookeeper cluster in multi region, we have leader in US EAST and
observers in US WEST, our data size is 1.3GB,network latency between leader
and observers is around 250ms, upon observer restart it is taking like
close to 30m for observer to serve traffic. Not sure why it's taking

In zookeeper what will happened if outstanding requests are high? we have

All,
I have multi data-center ldap cluster setup with other data-center with all

How to find actual size of zookeeper data since it store and operate from

Hi,
Do we need to configure any thing on observer nodes for SASL
authentication?
tcpKeepAlive=true ( this is not for sasl but just asking )
quorum.auth.enableSasl=true
quorum.auth.learnerRequireSasl=true
quorum.auth.serverRequireSasl=true
What will happen if i set these properties on observers
Any thoughts on what could be the reason for observers not able to connect
to followers/leader?

Hi,
Since with 3.5.5 version clients can watch on zoookeeper/confg znode for
the active zk servers, do we still need to give all the IPs of zk servers
to client? or can i give one IP or rr dns name to a client and client can
get server's list from the config znode to balance the connections?
All i want to do is avoid static IP as we have zk cluster in autoscalling
environment and IP is ephemeral there.

Hi,
What is the default value for this property, if i don't enable sasl and if
i don't define what will be the value?
quorum.auth.kerberos.servicePrincipal
Also what does this means "servicename/_HOST"
Thanks,
Ram

Hi,
What is the purpose of reading snapshot from disk while zk processes
starting up? i have a snapshot of ~2gb and it is taking time to read that
snapshot, hence cluster recovery time. Is it to get the last zxid of that
server?
```2020-01-21 23:11:24,510 [myid:106] - INFO
to properly remove old nodes and add new

Hi,
Does zookeeper cache the host IP? if so how long does it cache? I have a
zk cluster in autoscaling groups and when a new node comes up, other nodes
still resolving to old IP. Is there any setting to invalidate dns cache for
zookeeper? or is it jvm dns cache? until other nodes resolves to new
Hi Enrico,
I see same with both 3.4.5 and 3.4.14

But still happening for me, is there any config on zookeeper side to make
this fix to work?
