När jag kört ett tag i graph läget nu på en PDB via CDB, ser jag även konstiga värden på mycket annat. Cache Hit Ratio på 1200%, negativa värden på flera räknare, mm.
GUI delarna lirar inte riktigt heller, getMetrics ger en 500 och en NullPointer (beror på att pdbName skickas alltid, null om den inte ska användas, och det funkar
inte i alla metoder i OraMon.java klassen). Anger man en PDB i OraMon.jsp så blir det HTTP 0 status?? på getData och getMetrics knapparna.
2018-05-02
Lyckades köra JavaMonWeb i Debug läge med Tomcat 7 local server. Skapade en sanityCheck() metod med break points så jag kan debugga när vissa räknare blir negativa.
Dock svårt att hitta rätt LongDelta objekt, eftersom det finns över 1000 i listan i random ordning. Behöver spara undan det nånstans eller breaka inne i en LongDelta metod istället.
Checkar in detta i alla fall så länge.
