when a daemon crashes, it logs backtrace. unfortunately, it does not include process type that crashed. to find it out, we need to see the startup messages, which often are rotated away by that time.

initial suggestion was to log process name when crashing, but asaveljevs suggested including process type in every log message.

these process types probably should be shortened to 3 letters (2 are not enough - history syncer and heartbeat sender would be too similar).

before implementing, full list of mappings should be created - for example :

• history syncer - HSN
• heartbeat sender - HBS
