# Jenkins Plugin
|
||||
|
||||
The jenkins plugin gathers information about the nodes and jobs running in a jenkins instance.
|
||||
|
||||
This plugin does not require a plugin on jenkins and it makes use of Jenkins API to retrieve all the information needed.
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
## The Jenkins URL
|
||||
url = "http://my-jenkins-instance:8080"
|
||||
# username = "admin"
|
||||
# password = "admin"
|
||||
|
||||
## Set response_timeout
|
||||
response_timeout = "5s"
|
||||
|
||||
## Optional SSL Config
|
||||
# ssl_ca = /path/to/cafile
|
||||
# ssl_cert = /path/to/certfile
|
||||
# ssl_key = /path/to/keyfile
|
||||
## Use SSL but skip chain & host verification
|
||||
# insecure_skip_verify = false
|
||||
|
||||
## Optional Max Job Build Age filter
|
||||
## Default 1 hour, ignore builds older than max_build_age
|
||||
# max_build_age = "1h"
|
||||
|
||||
## Optional Sub Job Depth filter
|
||||
## Jenkins can have unlimited layer of sub jobs
|
||||
## This config will limit the layers of pulling, default value 0 means
|
||||
## unlimited pulling until no more sub jobs
|
||||
# max_subjob_depth = 0
|
||||
|
||||
## Optional Sub Job Per Layer
|
||||
## In workflow-multibranch-plugin, each branch will be created as a sub job.
|
||||
## This config will limit to call only the lasted branches in each layer,
|
||||
## empty will use default value 10
|
||||
# max_subjob_per_layer = 10
|
||||
|
||||
## Jobs to exclude from gathering
|
||||
# job_exclude = [ "job1", "job2/subjob1/subjob2", "job3/*"]
|
||||
|
||||
## Nodes to exclude from gathering
|
||||
# node_exclude = [ "node1", "node2" ]
|
||||
|
||||
## Worker pool for jenkins plugin only
|
||||
## Empty this field will use default value 5
|
||||
# max_connections = 5
|
||||
```
|
||||
|
||||
### Metrics:
|
||||
|
||||
- jenkins_node
|
||||
- tags:
|
||||
- arch
|
||||
- disk_path
|
||||
- temp_path
|
||||
- node_name
|
||||
- status ("online", "offline")
|
||||
- fields:
|
||||
- disk_available
|
||||
- temp_available
|
||||
- memory_available
|
||||
- memory_total
|
||||
- swap_available
|
||||
- swap_total
|
||||
- response_time
|
||||
|
||||
- jenkins_job
|
||||
- tags:
|
||||
- name
|
||||
- parents
|
||||
- result
|
||||
- fields:
|
||||
- duration
|
||||
- result_code (0 = SUCCESS, 1 = FAILURE, 2 = NOT_BUILD, 3 = UNSTABLE, 4 = ABORTED)
|
||||
|
||||
### Sample Queries:
|
||||
|
||||
```
|
||||
SELECT mean("memory_available") AS "mean_memory_available", mean("memory_total") AS "mean_memory_total", mean("temp_available") AS "mean_temp_available" FROM "jenkins_node" WHERE time > now() - 15m GROUP BY time(:interval:) FILL(null)
|
||||
```
|
||||
|
||||
```
|
||||
SELECT mean("duration") AS "mean_duration" FROM "jenkins_job" WHERE time > now() - 24h GROUP BY time(:interval:) FILL(null)
|
||||
```
|
||||
|
||||
### Example Output:
|
||||
|
||||
```
|
||||
$ ./telegraf --config telegraf.conf --input-filter jenkins --test
