The table below includes a list of all the metrics available:

metric name	type	description	component	node
kxi_rt_seq_leader	gauge	Leadership status of node	sequencer	all
kxi_rt_in_bytes_total	counter	Count of input bytes sequenced	sequencer	leader
kxi_rt_in_messages_total	counter	Count of input messages sequenced	sequencer	leader
kxi_rt_in_bytes	counter	Count of input bytes sequenced per directory	sequencer	leader
kxi_rt_in_messages	counter	Count of input messages sequenced per directory	sequencer	leader
kxi_rt_out_bytes_total	counter	Count of bytes merged	merger	all
kxi_rt_out_messages_total	counter	Count of messages merged	merger	all
kxi_out_bytes	counter	Count of bytes merged per directory	merger	all
kxi_out_messages	counter	Count of messages merged per directory	merger	all
kxi_rt_merge_queue_size	gauge	Merge instructions waiting in queue	merger	all
kxi_rt_truncated_log_age	gauge	Age of the last truncated log file in minutes	archiver	all

Note

• As well as exporting the total number of messages and bytes transferred (*_total metrics), RT exports the number of messages and bytes transferred per publisher, using a directory label set to session name.

• The sequencer leader metric is set on restart/leader change, therefore it is always up to date. The other sequencer metrics are updated every second, but only on the leader node and should be ignored for all other nodes.

• The merger metrics are all updated every second for all nodes.

• The value -1 of the truncated_log_age means that there is no garbage collected merged log file yet.
