Mikhail Petrov updated IGNITE-17554:
------------------------------------
Fix Version/s: 2.15
> {clientType}.ActiveSessions metrics are no updated in case of connection
> problems/lost
> --------------------------------------------------------------------------------------
>
> Key: IGNITE-17554
> URL: https://issues.apache.org/jira/browse/IGNITE-17554
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.13
> Reporter: Stepanov Ilya
> Assignee: Mikhail Petrov
> Priority: Minor
> Labels: ise
> Fix For: 2.15
>
> Attachments: ProxyServer.java
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Metrics "\{clientType}.ActiveSessions" are not updated correctly in case of
> connection problems.
>
> Steps to reproduce:
> 1) Start server
> 2) Start jdbc or thin client
> 3) Block port 10800 on the server host
> {code:java}
> iptables -A INPUT -p tcp --dport 10800 -j DROP {code}
> 4) Check "\{clientType}.ActiveSessions". We will see one connection.
> 5) Stop jdbc or thin client
> 6) Check "\{clientType}.ActiveSessions". We will still see one connection in
> "\{clientType}.ActiveSessions".
> 7) After about 2 hours, the metric will have a negative value = -1
