Withdraw of the 6.9.2 Release

Unfortunately, due to critical issues identified with version 6.9.2, we have decided to remove it and ensure it's no longer available for download. These issues impacted the ability to install or upgrade but none were security-related. We are diligently working to resolve these issues and are planning to release an updated version 6.9.3 in early May.

What if you've already upgraded?

For customers who have already upgraded to 6.9.2, no immediate action is required, as none of these issues are security-related. Once it's available, you will still be able to upgrade to 6.9.3 as normal. We appreciate your patience and trust as we continue to enhance our software to better serve you. Thank you for your understanding.

Application - Zookeeper Opspack

ZooKeeper is a distributed hierarchical key-value store, which is used to provide a distributed configuration service, synchronization service, and naming registry for large distributed systems. ZooKeeper was a sub-project of Hadoop.

ZooKeeper’s architecture achieves high availability through redundant services and ZooKeeper nodes store their data in a hierarchical name space, which maintains the consistency of a shared configuration service. ZooKeeper is utilized by a variety of large organizations including Rackspace, Yahoo!, Reddit, and eBay as well as open source enterprise search systems such as Solr.

What You Can Monitor Copied

Opsview Monitor contains all the performance metrics needed to monitor and keep your Zookeeper host online. Critical metrics are monitored and alerted on, to keep you aware of the number of Zookeeper file descriptors, the latency of Zookeeper, the Server mode and more.

Prerequisites Copied

This Opspack has been tested against ZooKeeper 3.3.0 and 3.4.9, other versions may be compatible but are not officially supported. Some of the service checks will only work with ZooKeeper version 3.4+ and the leader server.

If you are running a version older than 3.4, then you will need to disable the following service checks; approximate_data_size, ephemeral_count, followers, open_file_descriptor_percentage, pending_syncs, synced_followers and watch_count.

If you are monitoring a server that is in follower or standalone mode, then you will need to disable the following service checks; pending_followers and synced_followers as these metrics are only available on the leader machine.

If you are running ZooKeeper with a non-Unix operating system, you will need to disable the open_file_descriptor_percentage service check.
