New question #665679 on Graphite:
https://answers.launchpad.net/graphite/+question/665679
I am trying to create a seyren alert for my page render metric stored in
graphite.
My render stats are collected by ststsD and stored in graphite. The structure
is following:
stats.counters.renderCompleted.<country>.<placement_id>.<page_version>.count
e.g.
stats.counters.renderCompleted.US.123456.v1_1_03.count
stats.counters.renderCompleted.US.123456.v1_1_09.count
stats.counters.renderCompleted.US.654321.v2_1_05.count
stats.counters.renderCompleted.US.654321.v2_1_07.count
stats.counters.renderCompleted.UK.123456.v1_1_09.count
...
...
I want to create a seyren alert with graphite functions for US whenever the
last 2 hour render count average for ANY PLACEMENT ANY VERSION (e.g. group by
placement_id, page_version) falls below certain % of its (for that placement's
and version's) previous-day-same-time 2 hour window average.
I tried couple of ways, but not getting the the exact result I am intending:
1. using averageSeriesWithWildCards:
asPercent(
averageSeriesWithWildCards(
movingAverage(
scaleToSeconds(stats.counters.renderCompleted.US.*.*.count, 1),
'2hour'),
5),
averageSeriesWithWildCards(
movingAverage(
scaleToSeconds(
timeShift(stats.counters.renderCompleted.US.*.*.count, '1d'),
1),
'2hour'),
5)
)
2. Using groupByNode:
asPercent(
groupByNode(
movingAverage(
scaleToSeconds(stats.counters.renderCompleted.US.*.*.count, 1),
'2hour'),
4, 'averageSeries'),
groupByNode(
movingAverage(
scaleToSeconds(
timeShift(stats.counters.renderCompleted.US.*.*.count,'1d'),
1),
'2hour'),
4, 'averageSeries')
)
Will appreciate some help. Thanks in advance.
