Apache Zookeeper Input Plugin
This plugin collects variables from Zookeeper instances using the
mntr
command.
If the Prometheus Metric provider is enabled in Zookeeper use the
prometheus plugin instead with http://<ip>:7000/metrics
.
Introduced in: Telegraf v0.2.0 Tags: applications OS support: all
Global configuration options
In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.
Configuration
# Reads 'mntr' stats from one or many zookeeper servers
[[inputs.zookeeper]]
## An array of address to gather stats about. Specify an ip or hostname
## with port. ie localhost:2181, 10.0.0.1:2181, etc.
## If no servers are specified, then localhost is used as the host.
## If no port is specified, 2181 is used
servers = [":2181"]
## Timeout for metric collections from all servers. Minimum timeout is "1s".
# timeout = "5s"
## Float Parsing - the initial implementation forced any value unable to be
## parsed as an int to be a string. Setting this to "float" will attempt to
## parse float values as floats and not strings. This would break existing
## metrics and may cause issues if a value switches between a float and int.
# parse_floats = "string"
## Optional TLS Config
# enable_tls = false
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## If false, skip chain & host verification
# insecure_skip_verify = true
Troubleshooting
If you have any issues please check the direct Zookeeper output using netcat:
$ echo mntr | nc localhost 2181
