Ensure 'log_line_prefix' is set correctly

中レベル 1自動postgres

説明

The log_line_prefix setting specifies a printf-style string that is prefixed to each log line. If blank, no prefix is used. You should configure this as recommended by the pgBadger development team unless directed otherwise by your organization's logging policy. % characters begin "escape sequences" that are replaced with status information as outlined below. Requires the escapes %m %p %l %d %u %a %h (only %d %u %a %h when log_destination is syslog alone). Runs psql as ${PGUSER:-postgres} against ${PGDATABASE:-postgres}; set PGHOST/PGPORT and use ~/.pgpass (not PGPASSWORD, see 1.6/1.7) when peer authentication is not available.

チェック方法

監査方法: SQL クエリ

sql_query

out=$(psql -X -U "${PGUSER:-postgres}" -d "${PGDATABASE:-postgres}" -tAc "SELECT CASE WHEN (SELECT (d = 'syslog' OR (strpos(s, '%m') > 0 AND strpos(s, '%p') > 0 AND strpos(s, '%l') > 0)) AND strpos(s, '%d') > 0 AND strpos(s, '%u') > 0 AND strpos(s, '%a') > 0 AND strpos(s, '%h') > 0 FROM (SELECT current_setting('log_line_prefix') AS s, replace(current_setting('log_destination'), ' ', '') AS d) x) THEN 'compliant' ELSE 'noncompliant' END" 2>/dev/null) || exit 1; printf '%s\n' "$out"

期待される出力: compliant
