Elasticsearch Monitoring Tools
There are several elements to Elasticsearch monitoring that we’ve covered recently such as important metrics, plugins and performance testing tips. However, the only way to take advantage of all this information is by utilizing the right tools to oversee your Elasticsearch environment. There are several Elasticsearch tools that are designed for system management and maintenance, but only a select few make data immediately available in a way that is actionable and compatible with an external monitoring solution. Let’s look at the best resources for Elasticsearch monitoring.
Dealing with growing clusters can be a challenge and take up a lot of resources. A tool that is directly related to proactive monitoring, Marvel allows you to easily view performance in real time via cluster, index and node metrics. Enabling users to focus on memory usage over time (rather than just at a single point in time), Marvel is useful because it visualizes cluster behavior in a way that makes it easier to spot trends impacting your environment. The ability to explore data interactively and simplify APIs through Marvel makes for a more efficient workflow, and the fact that it is a free tool makes it even better!
Now operating under its replacement name cerebro, kopf is an open source and MIT-licensed web admin tool offering a simple method of performing common tasks on an Elasticsearch cluster. Not all APIs are covered with kopf, but its REST client allows you to discover the full potential of an API that is top of mind. kopf provides detailed analysis and contains enough features to be a valuable addition to your suite of Elasticsearch monitoring tools.
ElasticHQ is commonly used as a hosted on-demand monitoring tool for Elasticsearch clusters. With the option to either be installed as a plugin or downloaded/run locally, ElasticHQ monitors individual cluster nodes and gives insight into runtime metrics as well as configurations. Full cluster management, search and querying, and no software to install are major benefits of ElasticHQ and its flexibility adds more power to your monitoring efforts.
Elasticsearch Curator helps you to curate your Elasticsearch indices and snapshots in a variety of ways. Here are a few of the ways that Curator manage your Elasticsearch cluster:
- Obtains the full list of indices (or snapshots) from the cluster, named as an actionable list
- Iterates through a list of user-defined filters to progressively remove indices, or snapshots, from the actionable list as needed.
- Performs a wide variety of actions on the items which remain in the actionable list such as storage, automation, and the optimizing of static indices
