Monitoring list of metrics: Performance

Information about generic tag values

Following tags have common values across all measurements:

  • process- internal, set to statDataHead
  • head- type of protocol, that is S3
  • namespace- name of namespace
  • method - protocol-specific request method, that is GET, POST, READ, WRITE

Database monitoring_main

Performance metrics in this database are raw, each is split by data node, that is all have node and node_id tags.

Most of integer fields are increasing counters that is values that increase over time. Increasing counters restart from zero after datahead service restart.

Database monitoring_vdc

Performance metrics in this database are calculated values over whole VDC without reference to particular data node.

Most of values are:

  • Rates (number of requests per seconds)- for all measurements not ending by "_delta"
  • Delta values, increase of a counter from previous time stamp- for all measurements ending by "_delta"
  • Down sampled values (aggregated one point per day)- for all measurements ending by "_downsampled"
