Subject [jira] Updated: (GERONIMO-805) System Log Viewer portlet has a lot of untapped potential
Date Sat, 23 Jul 2005 20:56:45 GMT
     [ http://issues.apache.org/jira/browse/GERONIMO-805?page=all ]

Aaron Mulder updated GERONIMO-805:
----------------------------------

        Summary: System Log Viewer portlet has a lot of untapped potential  (was: System Log
Viewer portlet s-s-sucks!)
    Description: 
If would be helpful if this portlet:
 - would let you say "last N records"
 - would let you skip the end value or input an end value larger than the displayed line count
(to catch new rows)
 - would show line numbers of the matching lines, or let you specify bounds by time range
(using the same format as the records it shows)
 - would shows stack traces in the log formatted in a reasable way, yet without causing the
window to be too wide
 - would filter based on log messages of the specified log level or higher, and should actually
filter based on log level not based on lines that contain the same text as the name of the
log level (so a search on "WARN" wouldn't find a message like "13:45:11,760 DEBUG [SmapUtil$SDEInstaller]
277 read class attr -- '>WARN '", but would find an ERROR message)
 - would not cause an OutOfMemoryError when viewing a log file, particularly not for a log
file generated entirely that day (say, oh, 90k lines)
 - would in any case cap the display to some reasonable number of lines, say <= 1000


  was:
 - doesn't let you say "last N records"
 - doesn't let you skip the end value or input an end value larger than the displayed line
count (as if the log won't continue to grow!)
 - doesn't show line numbers of the matching lines
 - doesn't let you specify bounds by time range (which it does at least show).
 - shows stack traces as a single super-long line/message, forcing the page to be unacceptably
wide
 - filtering on log level actually greps the entire line for the log level, so a search on
"WARN" finds a message like "13:45:11,760 DEBUG [SmapUtil$SDEInstaller] 277 read class attr
-- '>WARN '".
 - searching on a level returns ONLY that level, not that level and higher
 - viewing a log file with less than a day's content (90k lines) causes an OutOfMemoryError
in the server (and viewing via the web site should in any case cap to some reasonable number
of lines, <= 1000?)



Sorry, didn't mean to hurt anybody's feelings.  :)
