We&#x27;ve been running OpenTSDB at a very large scale (~100k writes&#x2F;s) for the past year and a half and have been pretty happy with it. It&#x27;s not as reliable on the read side as something like ganglia and the query options aren&#x27;t as powerful as InfluxDB, but it can scale better than any other option I know of.<p>The ability to look back into the past and get full-resolution metrics is a huge deal. With Ganglia or Graphite (which  aggressively downsample old data) there&#x27;s a lot of squinting to try to make out patterns past a week or so.<p>That said, we also use HBase as our main data store, so we have a lot of experience with operating it. I&#x27;m not sure I could recommend OpenTSDB to an organization that lacks that expertise.
