Filtering tips
When filtering by source or destination IP, you can use the following in the filtering
criteria:
• a single address (2.2.2.2)
• an address range using a wild card (1.2.2.*)
• an address range (1.2.2.1-1.2.2.100)
You can also use the Boolean operator “or” to indicate multiple alternative
matches:
• 1.1.1.1 or 2.2.2.2
• 1.1.1.1 or 2.2.2.*
• 1.1.1.1 or 2.2.2.1-2.2.2.10
Most column filters require that you enter the column’s entire contents to
successfully match and filter contents; partial entries do not match the entire
contents, and so will not create the intended column filter.
For example, if the column contains a source or destination IP address (such as
192.168.2.5), to create a column filter, enter the entire IP address to be
matched. If you enter only one octet of the IP address, (such as 192) the filter will
not completely match any of the full IP addresses, and so the resulting filter would
omit all logs, rather than including those logs whose IP address contains that
octet.
Exceptions to this rule include columns that contain multiple words or long strings
of text, such as messages or URLs. In those cases, you may be able to filter the
column using a substring of the text contained by the column, rather than the
entire text contained by the column.
Note: Filters do not appear in Raw view, or for unindexed log fields in Formatted view.
When viewing real-time logs, you cannot filter on the time column: by definition of the real-
time aspect, only current logs are displayed.
