Summary
The idea behind the following few script are to log and report statistic usage of Firewall items. The script set consist of 3 scripts. • Update statistic • Report Statistics • Reset Statistic
Update Statistics
The update script makes use of the comment fields to store items descriptions and statistics (Bytes Used) A example comment filed for IP Firewall Filter looks like:
add action=passthrough chain=input comment="statistics - input traffic*43525369" disabled=no add action=passthrough chain=output comment="statistics - output traffic*63367747" disabled=no add action=passthrough chain=forward comment="statistics - forward traffic*421026065" disabled=no
The character * is used as a delimiter for the description and data portion.
The update script will update the combined total of tx and rx bytes for any item in ip firewall filter which has a * in the comment filed. Please note the original comet should have *0 The statistic stored are in bytes.
The Update Script
:local content
:local i
:local bytestotal
:local megstotal
:local bytescurrent
:local megscurrent
:local bytessaved
:local megssaved
:local ena
:local pos1
:local pos2
:log info "******************** starting - firewall filter usage update********************"
:foreach i in=[ /ip firewall filter find] do={
:set ena [/ip firewall filter get $i disabled]
:set content [/ip firewall filter get $i comment]
:if ($ena = false) do={
:if ([:find $content "*"] != "") do={
:local pos1 [:find $content "*"]
:local pos2 [:len $content]
:set bytessaved ([:pick $content ($pos1+1) $pos2])
:set megssaved ($bytessaved / 1048576)
:set bytescurrent [/ip firewall filter get $i bytes]
:set megscurrent ($bytescurrent / 1048576)
:set megstotal ($megscurrent + $megssaved)
:set bytestotal ($bytescurrent + $bytessaved)
:log info "-"
/ip firewall filter set $i comment="$[:pick $content 0 ($pos1)]*$bytestotal"
/ip firewall filter reset-counters $i
}
}
}
:log info "******************** ending - firewall filter usage update ********************"
The report script.
The report script will look for items in the ip firewall filter which has a * in the comment field. The reported unit would be un MB.

The Reset Script
The reset script will reset all counters back to a *0
:local i
:local content
:local ena
:local pos1
:local pos2
:log info "******************** starting - firewall- filter usage reset********************"
:foreach i in=[ /ip firewall filter find] do={
:set ena [/ip firewall filter get $i disabled]
:set content [/ip firewall filter get $i comment]
:if ($ena = false) do={
:if ([:find $content "*"] != "") do={
:local pos1 [:find $content "*"]
:local pos2 [:len $content]
/ip firewall filter set $i comment="$[:pick $content 0 ($pos1)]*0"
/ip firewall filter reset-counters $i
}
}
}
:log info "******************** ending - -firewall-filter usage reset ********************"
I have matching scripts for the following firewall items
