MongoDB Command monitor

Lib for GoLang MongoDB driver for command monitoring

Implements:

• total number of started queries with "app", "database", "collection", "command" labels
• total number of finished queries with "app", "database", "collection", "command" labels
• mongo query duration with "app", "database", "collection", "command" labels

Also, you can implement a custom metric collector by the Metrics interface.

Import into your project

go get github.com/DmitryTelepnev/mongo-command-monitor

import "github.com/DmitryTelepnev/mongo-command-monitor"

opts := driverOpts.Client()
...
opts.SetMonitor(commandMonitor.GetCommandMonitor(metrics.NewPrometheus("examples-app")))
...
client, err := driver.Connect(connectCtx, opts)

Run examples

cd examples; docker-compose up --build --force-recreate

Run benchmarks
