K-Logs-Test

K-logs-test helps you to be sure that your applications logs are getting into their destination (ElasticSearch) in a expected period of time.

In case the logs are taking more time than your team accept, k-logs-test will identify the problem and notify you. Also you can use the metrics exposed by the Prometheus Gateway.

How it works?

k-logs-test will create a pod in your kubernetes in a namespace you've defined.

export K_LOGS_CHANNEL="#k-logs"
export K_LOGS_ELASTIC_ENDPOINT="https://localhost:9200/fluentd"
export K_LOGS_NAMESPACE="monitoring"
export K_LOGS_POD_NAME="test-logs"
export K_LOGS_SLACK_ALERT_ENABLED="true"
export K_LOGS_THRESHOLD="2000"
export K_LOGS_WEBHOOK_URL="https://hooks.slack.com/services/XXXXXXX/YYYYYY/WWWWW"
export K_LOGS_PROM_ENABLED="true"
export K_LOGS_PROM_ENDPOINT="localhost"

And run the k-logs-test run without declaring any flags.
