I am struggling a bit here.
I've been tasked to set up various reports on palo firewall.
One of them is to create a custom report displaying all unused rules.
I've tried many things. I followed this link: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClcgCAC
which basically creates a report of used rules. I need exactly the opposite.
I've tried to use the query builder to set packet, bytes or count to zero hoping that I will be given a list of unused rules. Unfortunately it didn't work and I get "No matching records".
Anyone has any ideas how to achieve this?
At the bottom of your policies page, you can always just select "Highlight Unused Rules"
We even have a Tips and Tricks article on this:
If that will not suffice, then let me know and I will see if there is any other way here.
a couple of more things.. if you wanted something via the CLI which may be easier to read.. you can try this command:
show running rule-use rule-base <option> type unused vsys vsys1
That command will give you, in my opinion, an easier to read list than what the GUI is capable of giving you.
