Monitor Type: elasticsearch (Source)

Accepts Endpoints: Yes

Multiple Instances Allowed: Yes

Overview ๐Ÿ”—

This monitor collects stats from Elasticsearch. It collects node, cluster and index level stats.

This monitor collects cluster level and index level stats only from the current master in an Elasticsearch cluster by default. It is possible to override this with the clusterHealthStatsMasterOnly and indexStatsMasterOnly config options respectively.

A simple configuration that collects only default (non-custom) metrics looks like the following:

monitors:
- type: elasticsearch
  host: localhost
  port: 9200

Enhanced (custom) metrics ๐Ÿ”—

The monitor collects a subset of node stats of JVM, process, HTTP, transport, indices and thread pool stats. It is possible to enable enhanced stats for each stat group separately. Note that these metrics get categorized under the custom group if you are on host-based pricing. Hereโ€™s an example:

monitors:
- type: elasticsearch
  host: localhost
  port: 9200
  enableEnhancedHTTPStats: true
  enableEnhancedJVMStats: true
  enableEnhancedProcessStats: true
  enableEnhancedThreadPoolStats: true
  enableEnhancedTransportStats: true
  enableEnhancedNodeIndicesStats:
   - indexing
   - warmer
   - get

The enableEnhancedNodeIndicesStats option takes a list of index stats groups for which enhanced stats will be collected. A comprehensive list of all such available groups can be found here.

Note that the enableEnhancedIndexStatsForIndexGroups is similar to enableEnhancedNodeIndicesStats, but for index level stats.

Thread Pools ๐Ÿ”—

By default thread pool stats from the โ€œsearchโ€ and โ€œindexโ€ thread pools are collected. To collect stats from other thread pools specify the threadPools config option:

monitors:
- type: elasticsearch
  host: localhost
  port: 9200
  threadPools:
  - bulk
  - warmer
  - listener

Here is a list of valid thread pools by Elasticsearch version:

thread pool name ES 1.x ES 2.0 ES 2.1+
merge
optimize
bulk
flush
generic
get
snapshot
warmer
refresh
fetch_shard_started
fetch_shard_store
listener
management
percolate
suggest
force_merge

Collecting index statistics ๐Ÿ”—

By default, the configuration parameter indexes is empty, which means collect stats on all indexes. To collect statistics from a subset of indexes, set the configuration parameter indexes to a list of the index names you want to collect stats for.

The call to collect index statistics can be CPU-intensive. For this reason SignalFx recommends using the indexStatsIntervalSeconds configuration parameter to decrease the reporting interval for nodes that report index statistics.

Primaries vs total ๐Ÿ”—

By default the monitor collects a subset of index stats of total aggregation type (see docs for details). It is possible to enable index stats of primaries aggregation type too. Total for an index stat aggregates across all shards. Whereas, Primaries only reflect the stats from primary shards. An example configuration to enable index stats from Primary shards too:

monitors:
- type: elasticsearch
  host: localhost
  port: 9200
  enableIndexStatsPrimaries: true

Configuration ๐Ÿ”—

To activate this monitor in the Smart Agent, add the following to your agent config:

monitors:  # All monitor config goes under this key
 - type: elasticsearch
   ...  # Additional config

For a list of monitor options that are common to all monitors, see Common Configuration.

To see a list of metrics that will be emitted you can run agent-status monitors after configuring this monitor in a running agent instance.
