> What should the conversion factor be? (For dispatch lag, it’s 60 – five seconds of replication lag are equivalent to five minutes of dispatch lag.) Based on the last three months <https://grafana.wikimedia.org/d/000000489/wikidata-query-service?panelId=8&fullscreen&orgId=1&from=now-90d&to=now>, 5 minutes seems fine but we could go for 10 if needed. > Lag between different servers can differ significantly. Do we use the mean lag? The median? The maximum? Something else? (For dispatch lag, we seem to use the median.) As seen in the previously linked graph, there are some differences yes. I would at least ignore the ones under 1 minute, the median of the ones above that should give a good indication.
