Designing and Implementing a Migration Strategy to Move Archived Data from Graphite to InfluxDB

The EOS operations team has been using Graphite for many years in order to monitor and manage large-scale storage systems which are getting data from different CERN experiments, be it LHC experiments such as ATLAS, CMS, ALICE, etc. or non-LHC experiments such as AEGIS, DIRAC, etc. As data rate increases and as clusters are getting bigger, EOS is reaching the limits of a single Graphite node instance to monitor their infrastructure. So, the viable solution is to move to a different database such as InfluxDB. Moreover, InfluxDB is the standard time series metrics storage system provided and supported by the IT department at CERN. In this report, We will be discussing the designing and implementation of such a migration strategy to move archived data from Graphite to InfluxDB effectively.
