This plugin checks the docker container internal memory usage, it retrieves the values using docker stats. The plugin outputs also the performance data.
Requirements
- Docker 1.5.0 or higher
- The script requires sudo permissions due docker (this can be prevented if the nrpe user is added to docker group)
Usage
sudo ./check_container_memory.sh -w -c
Output
OK - if the Memory usage is under the warning and critical thresholds
WARNING - if the Memory usage is equal or over the warning threshold and it is under the critical threshold
CRITICAL - if the Memory usage is equal or over the critical threshold
UNKNOWN - if the container does not exist
Examples
$ sudo ./check_container_memory.sh container -w 80 -c 95
OK - MEMORY Usage = 4.82% | Memory Usage=0.05%;80;95;0;100
$ sudo ./check_container_memory.sh container -w 80 -c 95
CRITICAL - MEMORY Usage = 96.79% | Memory Usage=96.79%;80;95;0;100
$ sudo ./check_container_memory.sh notexist -w 80 -c 95
