Combining Multiple Scripts into 1

RouterOS Scripting
1

Hi All,

So, I’m way out of my depth here… I have some scripts that have been mashed together from info on the forum, but I want to combine them into a single one.

Basically what i need to do is the following:


Check if the main WAN connection has connectivity

  1. If UP, then:
  2. Make sure Backup4G interface is disabled (if not, then disable)
  3. Make sure VPN interface is enabled
  4. Log info Primary UP
  5. If DOWN, then:
  6. Log info Primary DOWN
  7. Check the backup connection’s quota limit (8GB)
  8. If over 8GB, make sure Backup4G interface is disabled (if not, then disable)
    2. If under 8GB then:
  9. Make sure VPN Interface is disabled (if not, then disable)
    2. Make sure Backup4G interface is enabled (if not, then enable)

rinse and repeat every 5 minutes

So far, these are the scripts I have:

Code to detect quota

:local traffic ([/file get counter.txt contents] / 1000 / 1000 / 1000)
#set the LTE quota in GB
:local limit 8
:local percent ($traffic*100 / $limit)
 
:if ($percent >= 90) do={/interface disable Backup4G}

Code to detect if primary WAN interface is UP

:if ([/ping 208.67.222.222 count=5] = 0) do={
:log info "Primary Appears Down"
/if ([interface get "PIA VPN" running] = true) do={interface disable "PIA VPN"}
/if ([interface get "Backup4G" running] = false) do={interface enable "Backup4G"}
} else={
:log info "Primary Appears Up"
/if ([interface get "Backup4G" running] = true) do={interface disable "Backup4G"}
/if ([interface get "PIA VPN" running] = false) do={interface enable "PIA VPN"}
}

Code to get traffic stats for quota

:local counter [/interface get "Backup4G" rx-byte]
:set $counter ($counter + [/interface get "Backup4G" tx-byte])
:local traffic
:if ([:len [/file find where name=counter.txt]] < 1 ) do={
/file print file=counter.txt where name=counter.txt;
/delay delay-time=2;
/file set counter.txt contents="0";
};
:local before value=[/file get counter.txt contents]
 
:if ($counter > $before) do={
/file set counter.txt contents=$counter
} else= {
:set $traffic ($counter+$before)
/file set counter.txt contents=$traffic
};

The above scripts are what I want to combine into a single workflow… If possible..

I have tried with multiple versions of “if” statements, but the syntax errors always get me.. and for some of them, I really don’t understand how they work (as I copy/pasta from the forum)..

Code for detecting the 4th of the month - (This runs once a day @ 1am, time synced with NTP)

if  ([:pick [/system clock get date] ([:find [/system clock get date] "/" ] + 1) 6 ] = "04") do={/file set counter.txt contents="0"}

Any help would be appreciated… Thank you
