Editing the Messages File

The messages file, APCMSGS, contains records in numerous formats. Two types of

entry records are of interest to users of SNAX/APC : K records and S records.

An entry record begins as shown in Table 3-2

K-Records (Internal Events)

K-Records record unusual conditions within SNAX/APC. Starting in column 7 is a code

defining whether the event is to be logged, an EMS event is to be generated—and, if so,

to which collector, or both, according to Table 3-3

Table 3-2. Entry Records

Column Number Content

1 A letter, identifying the kind of entry, where K identifies internal events

and S identifies SNA sense codes

2 to 5 A four-digit hexadecimal number identifying the particular message

6 A blank

Table 3-3. Code Conditions

Code Letter Code Action

I No event, no log message.

L Log message only.

E EMS event only, generated to the primary EMS collector.

En EMS event only, and generated to the alternate collector number n. The

value n can currently have the value 1, 2, or 3. Thus, if an EMS event is

to be generated to alternate collector number 1, for example, the code

appears as E1. Only this collector gets the message.

B Both a log message is generated, and an EMS event is sent to the primary

EMS collector.

Bnumber Both a log message and an EMS event are generated. The EMS event is

generated to alternate EMS collector specified by the variable number.

Thus, if a log message is to be generated, and an EMS event sent to

collector number 2, for example, the code appears as B2. EMS collector

number 2 is the only collector that receives the message.

S Some K-records have a logging disposition S. This is an internal notation

that facilitates the referral to the S-records to obtain a logging disposition

based on the relevant SNA sense code. It is recommended that the

logging dispositions of such K-records not be changed, but that the

logging dispositions of the S-records is modified, based upon the

pertinent sense code (see S-Records (SNA Sense Codes), below).
