ActiveMQ and Replicated LevelDB Store
I have standard 3 node ActiveMQ cluster.
I monitor it via JMX. And this is what I see:
Master:
StoreLimit=8589934592
StorePercentUsage=2
TempLimit=5368709120
TempPercentUsage=3
Slave1:
StoreLimit=8589934592
StorePercentUsage=93
TempLimit=5368709120
TempPercentUsage=146
Slave2:
StoreLimit=8589934592
StorePercentUsage=7
TempLimit=5368709120
TempPercentUsage=0
Actual filesystem state is:
Master:
du -hs /var/activemq/data/
266M /var/activemq/data
Slave1:
du -hs /var/activemq/data/
124M /var/activemq/data
Slave2:
du -hs /var/activemq/data/
119M /var/activemq/data
So question is what means
StorePercentUsage=93
TempPercentUsage=146
then used Replicated LevelDB Store
Or in another words why Replicated LevelDB Store ignores this settings
StoreLimit=8589934592
TempLimit=5368709120

Kevin Burton, this is the LevelDB post I was referring to.

As I ask previousely but in other words "What measured by StorePercentUsage?
How it measured?"
I have very strong suspicions that in upper described configuration this
counters measure temperature on moon or other random value.
in this time I sow
reasonable values on master
but on 1-st slave
StorePercentUsage=510
TempPercentUsage=146
and on 2-nd slave
StorePercentUsage=424

Hi,
I am a colleague of topic starter.
The question is: What to do if these values below are growing on Replicas:
StorePercentUsage=93
TempPercentUsage=146
Actually other things you mentioned are also interesting:
- Why StoreUsage for the three brokers seems unrelated to disk usage?
- Why three brokers in a LevelDB cluster have vastly different
StorePercentUsage values?
Are there any best practices on managing and monitoring ActiveMQ?

What's the question here? Why temp usage exceeds TempLimit? Why
StoreUsage for the three brokers seems unrelated to disk usage? Why three
brokers in a LevelDB cluster have vastly different StorePercentUsage
values? Something else?
Do you have Producer Flow Control (
http://activemq.apache.org/producer-flow-control.html) enabled?
