Scalelite Support#

BigBlueButton Exporter can be used alongside Scalelite. In fact the exporter doesn't need to know anything about Scalelite (or Scalelite about the exporter) since the exporter still needs to be configured to scrape metrics from the BigBlueButton server's API. See comment in Issue #31.

My CA_BUNDLE for the TLS_VERIFY environment variable is not working#

If you will specify the directory flavor, make sure the directory is filled with public keys of your trusted CA in PEM format.

If you will specify the file flavor (e.g. TLS_VERIFY=/app/CA_BUNDLE.txt), make sure the file contains an appended list of all your trusted PEM formatted CA's. Non-working example to denote the format:

... // PEM formated CA

... // PEM formated CA

... // PEM formated CA

All in One Monitoring Stack BrokenPipeError#

If you get a BrokenPipeError exception similar to:

This is caused by Prometheus closing the metrics scrapping HTTP request to the exporter because the request duration exceeds the Prometheus defined scrape_timeout value. The Prometheus config (prometheus.yaml) file bundled with the All in One Monitoring Stack has the default scrape_timeout set to 15 seconds. The recommended way of fixing this is to enable the RECORDINGS_METRICS_READ_FROM_DISK optimization which should dramatically reduce scraping times.

You could also override the scrape_timeout value for the bbb_exporter job but this should be only done in cases where enabling the RECORDINGS_METRICS_READ_FROM_DISK optimization is unfeasible.
