Calculate SLI/SLO metrics from ZMON's timeseries data

ZMON SRE SLO Metrics

WORK IN PROGRESS

Calculate SLI/SLO metrics using ZMON's KairosDB timeseries database.

Idea:

• Retrieve metrics such as latencies and error counts from KairosDB
• Aggregate metrics, weighted by requests/s
• Push metrics truncated to full minute timestamps into PostgreSQL
• Generate reliabilty reports (weekly, monthly, ..)

$ docker run -d -p 5432:5432 postgres:9.5
$ cat schema.sql | psql -h localhost -U postgres
$ cat sample_data.sql | psql -h localhost -U postgres
$ export DATABASE_URI='host=localhost user=postgres'
$ export KAIROSDB_URL=https://kairosdb.example.org
$ sudo pip3 install -r requirements.txt
$ python -m app.main

Configuration parameters:

OAUTH2_ACCESS_TOKENS_URL

Token endpoint URL.

CREDENTIALS_DIR

Folder with OAuth application credentials (client.json and user.json).

DATABASE_URI

PostgreSQL database connection string.

KAIROSDB_URL

KairosDB base URL.
