Hi folks, Any idea how we can assign a default value for empty tag with KV_MODE=xml? The reason is, we have a xml segment repeated multiple times under same parent/grandparent, as such same tag names (xpath) repeated multiple times. So one field for each tag name is extracted with a mv value. Now the issue is if some of the tag in the middle is empty, it will mess up the mv index in these fields. And we need the full xpath as the field name, so it is hard to do a manual generic field extraction ($1::$2) either.  A quick thought is if we can fill up a special value in the raw, then all mv fields will stay well aligned. But is this the only option? Any suggestion or better solution? Or can we do it at search time with sonething like " | rex field=ccnumber mode=sed ..."   Thanks a lot     ... View more

Hi I read a post saying "Using wildcard monitor statements over deep file systems has a significant performance impact, so if this can be avoided it would be of benefit." I'd like to better understand what that exactly means? What kind of "performance impact" it is, cpu, memory, disk, IO? We have a UF 6.5 running on a Linux box, monitor a folder with about 460 files. The folder has 8 levels sub-folders, then come log files. Is this a DEEP file systems? When I put the wildcard at the second level of sub-folder, monitor this whole folder tree in one stanza, it shows huge memory consumption percentage, and the log server closes to freezing. When I specify every individual log file in its own stanza without using wildcard, everything works well without any performance issue. The issue is, the second level of sub-folder names are dynamic, we have to use an ad-hoc script to manually build configuration file for all directories/files every day. We'd really like a better solution to avoid this daily manual intervention. Which makes me doubt, when UF monitors one big folder tree, does it process them all in one thread? Any other explanation for this, and any solution? Thanks... ... View more
