HPA Metrics summary Log File Reader metrics

Metrics produced by the Log File Reader feature.

Line count metrics

For each collection cycle, the reader counts the number of matching lines per unique combination of key alias and extract field values.

Path pattern:

Hpa|LogFile|{reader}|{keyAlias}|{extractField1}|{extractField2}|...:value
  • {reader} — the reader name from the configuration
  • {keyAlias} — the alias of the matched key value (or the raw value if no alias is defined)
  • {extractFieldN} — each extracted field value, in order

If no extract fields are configured, the path is simply:

Hpa|LogFile|{reader}|{keyAlias}:value

The value is the number of matching lines seen during the collection interval (PER_INTERVAL semantics).

Examples:

Configuration Metric path Meaning
reader CTM_DAILY, key alias OK, extract fields JOB_A and PROD Hpa|LogFile|CTM_DAILY|OK|JOB_A|PROD:value Number of lines with status OK for job JOB_A in PROD
reader APP_ERRORS, key value ERROR, no extract fields Hpa|LogFile|APP_ERRORS|ERROR:value Number of ERROR lines

Diagnostic metric

Each reader also reports the number of files currently matching its file-name-regex:

Hpa|LogFile|{reader}:filesMatched

Value sanitization

Special characters in extracted values are replaced to produce valid metric paths:

  • | and : are replaced with _
  • Empty values are replaced with (empty)
