Small GoLang util to collect metrics form Prometheus and Docker
Example:metrics --nodes=systemA,systemB --name=foo --timeout=60s --interval=500ms
Collects metrics from systemA and systemB every 500ms for 60s and saves them to foo_YEAR_MONTH_DAY.csv
By default, each select node must provide access to the docker api over port 2376 and access to the prometheus node agent over port 9100.
| Name | Default | Usage |
|---|---|---|
| nodes | nil |
list of urls to connect to seperated with , |
| name | |
prefix used for the log file |
| timeout | -1 |
timeout before stopping to collect data, -1 means no timeout |
| interval | 1s |
interval between polling data from all nodes |
| docker | true |
indecate if docker metrics should be collected |
| dport | 2376 |
port used to connect to docker api |
| pport | 9100 |
port used to connect to prometheus node agent |
Use Ctr+C to terminate the process if no timeout is defined.
The output is a csv file with the following columns:
| Name | Description |
|---|---|
| timestamp | current timestamp |
| HId | node name |
| cpu_user | cpu used py user in percent |
| cpu_system | cpu used py system in percent |
| cpu_idle | cpu idle in percent |
| cpu_iowait | cpu used py iowait in percent |
| forks | number of forks |
| disk | disc usage |
| load | running load average (1 minute) |
| mem_available | available memory in bytes |
| mem_total | total memory in bytes |
| net_rev | bytes received |
