## Zookeeper Input Plugin
|
|
|
|
The zookeeper plugin collects variables outputted from the 'mntr' command
|
|
[Zookeeper Admin](https://zookeeper.apache.org/doc/current/zookeeperAdmin.html).
|
|
|
|
### Configuration
|
|
|
|
```toml
|
|
# 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"
|
|
|
|
## Optional TLS Config
|
|
# enable_tls = true
|
|
# 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
|
|
```
|
|
|
|
### Metrics:

Exact field names are based on Zookeeper response and may vary between
|
|
configuration, platform, and version.
