Collector Event Messages

EMS Manual—426909-005

20-25

521: ZEMS-EVT-LOGGING-STOPPED

ZEMS-TKN-GENTIME, -LOGTIME, -CPU, -PROC-DESC, -PIN, -NODENUM,

and -USERID

are standard EMS tokens. For more information, see Section 14, EMS Definitions.

ZEMS-TKN-SUBJECT-MARK (shared)

is the standard EMS token that immediately precedes each subject token. This

event message has one subject token:

ZEMS-TKN-COLLECTOR (nonshared)

specifies the collector type. This token has one of two values: ZEMS-SUBJ-

PCOLL (or 1) for the primary collector and ZEMS-SUBJ-ACOLL (or 2) for the

alternate collector.

ZEMS-TKN-LOGSTOPREASON (nonshared)

specifies the reason the collector stopped logging. The two main causes of this

event are expressed by the token values ZEMS-VAL-DISCFAILED and ZEMS-

VAL-NOROTATE.

ZEMS-TKN-ACTION-NEEDED (nonshared)

specifies whether some action is required (in this case because the collector

stopped logging). The token value here is TRUE.

ZEMS-TKN-ACTION-ID (nonshared)

has the value 0. The value is the same in the corresponding action-completion

message, ZEMS-EVT-FILESWITCH (514).

Cause. A primary or alternate collector cannot log event messages to a log file. This

event message is written to the log file when access to the file is restored, and it is

forwarded to any distributor waiting on a STATUS command from the collector. This

message is an action-attention message. The corresponding action-completion

message is ZEMS-EVT-FILESWITCH (514). The two main causes of this event are:



The last of the available log files in the logging subvolume is full, and the files

cannot be rotated (purged and recycled). See the fields ZCOL-MAXFILENNNN

and -ROTATEFILES in CONTROL Command (ZEMS-CMD-CONTROL)

page 19-34.



A problem exists with the disk device. See 515: ZEMS-EVT-COLL-DISC-FAILED

on page 20-14.

Effect. Logging stops. The primary collector eventually runs out of buffer space.

Recovery. If the maximum number of log files (given by ZCOL-MAXFILENNNN) is

already in use, you can do one of four things to resume logging:



Increase the value of ZCOL-MAXFILENNNN, using the CONTROL command or

the MAXFILE parameter of EMSCCTRL.
