Invantive Trace voortaan in NDJSON-formaat

Wiki (nl)
1

Vanaf versie 20.2.70 wordt het tekst-gebaseerde opslagformaat voor Invantive Trace vervangen door het NDJSON-formaat. Dankzij het NDJSON-formaat is het eenvoudiger om grote aantallen tracebestanden te doorzoeken. Ook wordt het eenvoudig om tracebestanden te laden in Amazon CloudWatch en ElasticSearch.

Het NDJSON-formaat heeft een regel per melding in JSON-formaat:

{"Message":"Invantive trace forwarder started.","MessageCode":null,"Occurred":"2021-10-21T17:05:46.8931234Z","Id":2,"ThreadId":1,"SessionId":"WPF-OnStartup-23e28338-f688-4df9-bbad-5d66ca2ea5de","PoolIdentityId":null,"CallingProviderAlias":null}

De tracebestanden kunnen ook opgevraagd worden via Invantive SQL met bijvoorbeeld:

select fle.file_path
,      msg.id
,      msg.thread_id
,      msg.session_id
,      msg.pool_identity_id
,      msg.message_code
,      msg.occurred_utc
,      msg.message_text
