Everyone needs a monitor
This project is intended to be used with fluentd, so you can retrieve metrics from host/docker. Then you can do whatever you want, I suggest storing the metrics on ElasticSearch because you will be able to visualize them with kibana
Simply run this command on your docker host
docker run \
--name log_bedel \
-v /var/run/docker.sock:/var/run/docker.sock \
-e INTERVAL_SECONDS=60 \
martinsthiago/bedel_monitor
If you run docker logs log_bedel you should be able to see the following output:
{
"disk": {
"total": 290,
"used": 74,
"free": 216,
"usage_percentage": 25
},
"memory": {
"total": 5443,
"used": 4831,
"free": 612,
"usage_percentage": 89
},
"cpu": {
"usage_percentage": 18
},
"docker": {
"version": "1.11.2",
"containers": [
{
"id": "57cf1949854a4b68919a75210fdf343087c6e8a5f9042f52bcc83be9e69d5d73",
"names": [
"/rangsapi_mongo_1"
],
"image": "mongo:3",
"status": "Up About an hour",
"stats": {
"memory": {
"limit": 5443,
"used": 102,
"swap": 0,
"usage_percentage": 2
}
}
}
]
}
}Why JSON? If you have a log collector server, it will be easy to parse metrics
- Retrieve container cpu usage %
- Improve errors handling
- v0.2.1 Added auto override for time argument (short times cn harm host cpu metric)
- v0.2.0 Added swap usage and improved disk metrics
- v0.1.0 Added cpu usage into container metrics
- v0.0.5 Changed fullname separator from "/" to "_"
- v0.0.4 Fixed container fullname
- v0.0.3 Logging metrics by type
- v0.0.2 Improved memory monitor to retrieve data similar to htop
- v0.0.1 Logging infos of host/disk/cpu/memory/docker
