Splunk


Events before or after X seconds
- Need manually edit the url to remove unneeded queries

You might be hitting this limit (from limits.conf):
  1. maxchars = <integer>
  2. * Truncate _raw to this size and then do auto KV.
  3. * Defaults to 10240 characters.
I have a field that is more than 10,000 characters. I updated props.conf to include
  1. [source::log.txt]
  2. TRUNCATE=20000

One of the most powerful features of Splunk software is its ability to extract fields from events when you search, creating structure out of unstructured data. To make sure field extraction works as intended, use the following string syntax (using spaces and commas is fine):
key1=value1, key2=value2, key3=value3 . . .
Splunk software's automatic field extraction is worth the size difference.
Splunk software knows how to index. It will catch up where it left off so you won't lose logging data.

When you export large amounts of data using the Export button, the session might timeout before the export is complete. You can extend the session timeout limit.
  1. Click Settings > Server Settings > General Settings.
  2. In the Splunk Web section, increase the number in the Session timeout field.
  3. Click Save.
