Constants ¶
const CollectorNameAndVersion = "pganalyze-collector " + CollectorVersion
const CollectorVersion = "0.56.0"
const QueryTextCollector string = "<pganalyze-collector>"
QueryTextCollector - Query generated by the pganalyze collector itself.
const QueryTextInsufficientPrivs string = "<insufficient privilege>"
QueryTextInsufficientPrivs - We did not have permissions to read this query text.
const QueryTextTruncated string = "<truncated query>"
QueryTextTruncated - Query was unparsable and is exactly track_activity_query_size-1 long. Only applies to query text from pg_stat_activity. This can be mitigated by raising track_activity_query_size.
QueryTextUnavailable - We only have the pg_stat_statement queryid for this query, not the actual query text. This occurs when there is high churn on the pg_stat_statements data and the less frequent query text collection didn't contain the text anymore for a query ID we saw earlier. Can be mitigated by increasing pg_stat_statements.max.
const QueryTextUnparsable string = "<unparsable query>"
QueryTextUnparsable - Query was unparsable and we don't know why. This could be because of the pg_query parser not yet understanding the syntax of newer Postgres versions.
const TruncatedQueryMarker string = "/* truncated-query */ "
TruncatedQueryMarker - Added to queries that were truncated and caused a parsing error, but we were able to "fix" to allow grouping in the UI

Functions ¶
func BoolPtrToBool ¶
func CleanHTTPError ¶ added in v0.41.0
Removes duplicate URLs added by retryablehttp

Clean up a created temporary file, reporting any errors to the log
func FingerprintQuery ¶
FingerprintQuery - Generates a unique fingerprint for the given query
func FingerprintText ¶ added in v0.42.1
FingerprintText - Generates a fingerprint for static texts (used for error scenarios)
func HttpRedirectToApp ¶ added in v0.43.0
func HttpRedirectToApp(w http.ResponseWriter, r *http.Request)
HttpRedirectToApp - Provides a HTTP redirect to the pganalyze app
func IntPtrToInt ¶
func IntPtrToString ¶
func IsUtilityStmt ¶
IsUtilityStmt determines whether each statement in the query text is a utility statement or a standard SELECT/INSERT/UPDATE/DELETE statement.
func NormalizeQuery ¶
