## install
|
|
|
|
The check requers python3. Using a virtual env is advised for testing :
|
|
|
|
```
|
|
pip -m venv ~/venv
|
|
source ~venv/bin/activate
|
|
```
|
|
|
|
Clone the repo, then install with pip3 from it :
|
|
|
|
```
|
|
pip3 install .
|
|
pip3 install .[dev]
|
|
pip3 install .[test]
|
|
```

## config file
|
|
|
|
All global and service specific parameters can be specified via a config file has follows:
|
|
|
|
```
|
|
[options]
|
|
endpoints = https://10.20.199.3:8008, https://10.20.199.4:8008,https://10.20.199.5:8008
|
|
cert_file = ./ssl/benoit-dalibo-cert.pem
|
|
key_file = ./ssl/benoit-dalibo-key.pem
|
|
ca_file = ./ssl/CA-cert.pem
|
|
timeout = 0
|
|
|
|
[options.node_is_replica]
|
|
lag=100
|
|
```
|
|
## thresholds
|
|
|
|
The format for the threshold parameters is "[@][start:][end]".
|
|
|
|
* "start:" may be omitted if start==0
|
|
* "~:" means that start is negative infinity
|
|
* If `end` is omitted, infinity is assumed
|
|
* To invert the match condition, prefix the range expression with "@".
|
|
|
|
A match is found when : start <= VALUE <= end
|
|
|
|
For example, the followinf command will raise :
|
|
|
|
* a warning if there is less than 1 nodes
|
|
* a critical if there are no nodes
|
|
|
|
```
|
|
check_patroni -e https://10.20.199.3:8008 cluster_has_replica --warning @1 --critical @0
|
|
