* DiskstatCollector: cast part_max_used metric to int * Add uint types to GangliaSink and LibgangliaSink * Use new sink instances to allow multiple of same sink type * Update sink README and SampleSink * Use new receiver instances to allow multiple of same receiver type * Fix metric scope in likwid configuration script * Mention likwid config script in LikwidCollector README * Refactor: Embed Init() into New() function * Refactor: Embed Init() into New() function * Fix: MetricReceiver uses uninitialized values, when initialization fails * Use Ganglia configuration (#44) * Copy all metric configurations from original Ganglia code * Use metric configurations from Ganglia for some metrics * Format value string also for known metrics * Numa-aware memstat collector (#45) * Add samples for collectors, sinks and receivers * Ping InfluxDB server after connecting to recognize faulty connections * Add sink for Prometheus monitoring system (#46) * Add sink for Prometheus monitoring system * Add prometheus sink to README * Add scraper for Prometheus clients (#47) Co-authored-by: Holger Obermaier <holgerob@gmx.de> Co-authored-by: Holger Obermaier <40787752+ho-ob@users.noreply.github.com>
