2017-10-24stats_test: Extend check to include test for counter group name manglingHarald Welte1-0/+24
In Change-Id Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 we introduce name mangling to replace any '.' in counter (group) names to be converted to ':'. Let's test for this functionality explicitly as part of the stats_test. Change-Id: Ie35682aa79526e2ffeab6995cd640b7847d855bf
2017-10-24rate_ctr: Enforce counter (and ctr_group) names are valid identifiersHarald Welte1-42/+42
As rate counters are automatically exposed on the CTRL interface, we need to make sure they don't contain special characters such as '.' which are not permitted/supported by CTRL. In order to be able to run old versions of osmocom programs with libosmocore versions after this commit, we introduce some special name mangling: Any '.' in the names are replaced with ':' during counter group registration, if valid identifiers can be obtained this way.

2015-10-28stats: Add stat_item for value monitoringJacob Erlbeck1-0/+0
This commit adds instrumentation function to gather measurement and statistical values similar to counter groups. Multiple values can be stored per item, which can be retrieved in FIFO order. Getting values from the item does not modify its state to allow for multiple independant backends (e.g. VTY and statd). When a new value is set, the oldest value gets silently overwritten. Lost values are skipped when getting values from the item. Sponsored-by: On-Waves ehf
