Today, we are happy to announce the release of Elasticsearch Marvel 1.1.1. This is a bug fix release, fixing an issue with the correct interpretation of timeout settings by the Marvel agent. Although this bug is not critical, we felt it was important enough to justify a release.
While this release is beneficial for all users, we especially recommend it if you are experiencing occasional timeout errors such as these:
[2014-05-12 21:52:41,133][ERROR][marvel.agent.exporter ] [Robert da Costa] error connecting to [10.255.255.1:9200] java.net.SocketTimeoutException: connect timed out
To upgrade, you must install the latest Marvel plugin on all your ES nodes. As with any other Java plugin, you will need to restart nodes (one by one) in order for the version to become active. You may follow a similar procedure to the rolling upgrade of Elasticsearch itself, described in more details here.
As always, we welcome all feedback so we can continue improving Elasticsearch Marvel. Please send questions, praise or pains to the Elasticsearch User Mailing List.
