Asks Prometheus for the average of each clock hour of the last
days days, for the Daily Pattern tab. The average Prometheus gives at a
time covers the hour before it, so it is filed under the hour that starts
one hour earlier, in the time zone of the app.
Usage
get_hourly(urlq, metric, days = 30, end_time = Sys.time())
Arguments
- urlq
Prometheus query_range url.
- metric
Name of the metric, one of metrics.
- days
Number of days, up to the start of the current hour.
- end_time
The time to count back from, by default now.
Value
A data frame with one row per hour: date (a Date), hour (0 to
23) and value. It has no rows when the server has no readings of the
metric in that time, and is NULL, with a message, when the server
cannot be reached.

if (FALSE) { # \dontrun{
url <- "http://pip1.crabdance.com:1507/api/v1/query_range"
