Below is the description of the metrics returned by 'getMetrics' REST endpoint.
The general format of the output is complient with Prometheus text-based format
which can be found here: https://prometheus.io/docs/instrumenting/exposition_formats/#text-based-format
GLOBAL
global_host_system_memory_bytes - Total host system memory in bytes.
global_memory_available_bytes – Memory available to our application in bytes. This is equal to global_host_system_memory_bytes * memproportion where memproportion represents the maximum percentage of system memory consumed by all of the Collabora Online, after which we start cleaning up idle documents. This parameter can be setup in loolwsd.xml.
global_memory_used_bytes – Total memory usage: PSS(loolwsd) + RSS(forkit) + Private_Dirty(all assigned loolkits).
global_memory_free_bytes - global_memory_available_bytes - global_memory_used_bytes
LOOLWSD
loolwsd_count – number of running loolwsd processes.
loolwsd_thread_count – number of threads in the current loolwsd process.
loolwsd_cpu_time_seconds – the CPU usage by current loolwsd process.
loolwsd_memory_used_bytes – the memory used by current loolwsd process: PSS(loolwsd).
FORKIT

KITS
kit_count – total number of running kit processes.
kit_unassigned_count – number of running kit processes that are not assigned to documents.
kit_assigned_count – number of running kit processes that are assigned to documents.
kit_segfault_count - number of kit processes terminated with SIGSEGV or SIGBUS signals since the start of application.
kit_lost_terminated_count - number of kit processes that were lost by loolwsd and were terminated by cleanup mechanism.

document_resource_consuming_abort_started_count - number of resource consuming documents for which the termination process started (SIGABRT/SIGKILL signal was sent to the associated kit process) but they are still considered active by loolwsd. This is relevant because it shows how many resource consuming docs possibly could not be terminated or for which the termination process is too long.
