Parsoid/Performance Metrics
Appearance
< Parsoid
These are the metrics currently aggregated in Parsoid using StatsD and Graphite.
Note, timing = start of get_article/post_article call till response return.
Metric | Definition |
html2wt.init | measures time elapsed, in ms, between start of request and beginning of serialization |
html2wt.init.domparse | a component of html2wt.init, measures time elapsed, in ms, between parsing html string to DOM tree |
html2wt.size.input | length of the request's html string |
html2wt.size.output | length of the response string |
html2wt.selser.serialize | timing of selective serialization. i.e Dom Diff showed changes, so selective serialization of those changes. |
html2wt.selser.domDiff. | time to Dom diff generation. |
html2wt.full.serialize | timing of non-selective serialization. i.e no Dom Diff / no old source, fall back to non-selective serialization. |
html2wt.total | timing from request to response, of html2wt requests. |
wt2html.total | timing from request to response, of wt2html requests. |
wt2html.pageWithOldid.init | measures time elapsed, in ms, between start of request and the beginning of parsing using an Oldid. |
wt2html.pageWithOldid.parse | timing of wt2html requests parsed using an Oldid, a component of wt2html.total. |
wt2html.pageWithOldid.size.input | length of wt src (string) to be parsed. |
wt2html.pageWithOldid.size.output | length of response string parsed using the parsePageWithOldid route. |
wt2html.wt.init | measures length of time, in ms, elapsed between start of request and beginning of parsing using wt. |
wt2html.wt.parse | timing of wt2html requests parsed using wt, a component of wt2html.total. |
wt2html.wt.size.input | length of request string (wt) to be parsed. |
wt2html.wt.size.output | length of the response string parsed using the parseWt route. |
wt2html.redirectToOldid | count of wt2html requests that were redirected to the old revision using an old id. |
heap.rss, heap.total & heap.used | measures, in bytes, the memory usage of the Node process. |
