Supervisor Log Codes

[edit on GitHub]

When running services with the Chef Habitat Supervisor you’ll see log output similar to this:

redis.default(SR): Initializing
redis.default(SV): Starting
redis.default(O):

The letters in parentheses are called “log keys” and signify what type of log message is being shown. This can be useful for log filtering.

They are mostly organized by the part of the Chef Habitat Supervisor code base that they are running from, so they often are of value to somebody troubleshooting problems in the Chef Habitat Supervisor source code.

The meanings of the keys are as follows:

Key	Description
CE	Census
CFG	Global configuration
CS	Create service: When a service is being started
ER	Errors
FW	Generic file watcher
HG	Messages from the HTTP gateway
MN	Main
MR	Manager
O	Standard output
PH	Package hooks
PK	Package
PT	Path
PW	Peer file watcher
SC	Service configuration
SH	Starting a shell with hab sup sh
SI	Unix signals
SOT	Structured output
SR	Service runtime
SU	Service updater
SV	Supervisor
SY	“sys” utility
UCW	User-config watcher
UR	Users utility
UT	Utilities
