New page

nft can display notifications of ruleset updates through:

<source lang="bash">
% nft monitor
</source>

This subscribes ''nft'' to any kind of ruleset update.

You can filter out events per type of:

* object: tables, chains, rules, sets and elements.
* event: new and destroy.

The output format can be:

* plain text (ie. native nft format)
* xml
* json

The following example shows how to follow track of rule updates only:
<source lang="bash">
% nft monitor rules
</source>
In case, you only want to receive only new rules:
<source lang="bash">
% nft monitor new rules
</source>
== A bit more developed example ==

Type the following in a terminal:
<source lang="bash">
term1% nft monitor
</source>
From a different terminal, if you type this:
<source lang="bash">
term2% nft add table inet filter
term2% nft add chain inet filter forward
term2% nft add rule inet filter forward counter accept
term2% nft flush table inet filter forward
term2% nft flush ruleset
</source>
Then, if you go back to the ''term1'', you'll see:
<source lang="bash">
term1% nft monitor
add table inet filter
add chain inet filter forward
add rule inet filter forward counter packets 0 bytes 0 accept
delete rule inet filter forward handle 4
delete chain inet filter forward
delete table inet filter
</source>
