How to see how long the internet connection has been up?

[AP3]

Hi All,

I just got my first Asus router (AC86U), and on the advice of others, installed the Merlin firmware (386.5).

My question isn't specific to Merlin I guess, but how can I see how long the internet has been connected (not router uptime)?

I used to use a Fritz!Box, and it was very easy to find it on that.

Cheers,
Andy

If you have user scripts turned on, you can watch the log for "wan-event" with the argument "connected".

To further that, you make your own wan-event script to write to a custom log or write a custom message to the syslog each time the wan either connects or disconnects. I have a wan-event script that emails me when the wan connects and what the public side IP is.

More info is here;

Here is a Merlin specific solution using a user created script, I hope it works for others

This requires having a wan-event file I do believe to trigger the wan-event messages in the log... Im not sure how else to capture the wan up/down in the log

I had a function for something similar, I scratched this together to take advantage of the idea from @Jeffrey Young

Enable jffs/scripts
From SSH terminal
cd/jffs/scripts
nano wantime.sh
Copy and paste code box below, ctrl+x and y to save
dos2unix /jffs/scripts/wantime.sh
chmod a+rx wantime.sh
sh wantime.sh

#!/bin/sh
# Calc difference from last wan-event connected to now   written by Maverickcdn March 20 2022
run_epoch=$(date +%s)   # current epoch time
# find last wan-event connected
findlast=$(cat /tmp/syslog.log | grep "wan-event" | grep "args: * connected" | tail -n1)   # search log for most recent wan-event connected
[ -z "$findlast" ] && findlast=$(cat /tmp/syslog.log-1 | grep "wan-event" | grep "args: * connected" | tail -n1)   # check older logs if not found prior
[ -z "$findlast" ] && printf "Couldn't find last wan-event connected event in logs... exiting. \n" && exit 0   # nothing to calculate... exit
fnd_mth=$(echo $findlast | awk '{print $1}')   # found month
fnd_day=$(echo $findlast | awk '{print $2}')   # found day
fnd_time=$(echo $findlast | awk '{print $3}')   # found time
# convert found month to num

tmp_mth=${month_list%%$fnd_mth*}
month_fnd=${#tmp_mth}
month_num=$((month_fnd/3+1))
year=$(date +%Y)
[ "$fnd_day" -gt "$(date +%d)" ] && [ "$month_num" -eq "$(date +%m)" ] && year=$((year - 1))   # month same but higher fnd_day = previous year
[ "$month_num" -gt "$(date +%m)" ] && year=$((year - 1))   # if month is higher = previous year
log_date_fnd=$(echo "${year}-${month_num}-${fnd_day} ${fnd_time}")   # format found date/time for date -d
saved_wan_epoch=$(date -d "$log_date_fnd" +%s)   # convert wan-event date to epoch

# calc difference function
F_calc_lease() {
        wan_lease_years=0 ;wan_lease_days=0 ;wan_lease_hours=0 ;wan_lease_mins=0 ;wan_lease_secs=0   # set for output

                wan_lease_days=$((epoch_diff / 86400))
                epoch_diff=$((epoch_diff - (86400 * wan_lease_days)))
        fi
        if [ "$epoch_diff" -gt 3600 ] ; then   # hours
                wan_lease_hours=$((epoch_diff / 3600))
                epoch_diff=$((epoch_diff - (3600 * wan_lease_hours)))
        fi
        if [ "$epoch_diff" -gt 60 ] ; then   # mins
                wan_lease_mins=$((epoch_diff / 60))
                epoch_diff=$((epoch_diff - (60 * wan_lease_mins)))
        fi
        wan_lease_secs="$epoch_diff"                    # secs

        printf "Last wan-event connected event found        : %s \n" "$findlast"
        printf "WAN uptime since last connected event       : "
        [ "$wan_lease_years" -gt 0 ] && printf "%s yr(s) " "$wan_lease_years"
        [ "$wan_lease_days" -gt 0 ] && printf "%s day(s) " "$wan_lease_days"
        [ "$wan_lease_hours" -gt 0 ] && printf "%s hr(s) " "$wan_lease_hours"
        [ "$wan_lease_mins" -gt 0 ] && printf "%s min(s) " "$wan_lease_mins"
        printf "%s sec(s) \n" "$wan_lease_secs"
} ### calc_lease

F_calc_lease
exit 0

My results

MavMAIN|>/jffs/scripts| sh wantime.sh
Last wan-event connected event found        : Mar 13 03:00:05 custom_script: Running /jffs/scripts/wan-event (args: 0 connected)
WAN uptime since last connected event       : 7 day(s) 17 hr(s) 24 min(s) 12 sec(s)

Lines 5,6 and 7 might be better off with these instead if you dont use a wan-event script already.... just a guess, maybe someone else can suggest something else to search for when wan goes up

findlast=$(cat /tmp/syslog.log | grep "wan: finish adding multi routes" | tail -n1)
[ -z "$findlast" ] && findlast=$(cat /tmp/syslog.log-1 | grep "wan: finish adding multi routes" | tail -n1)   # check older logs if not found prior
[ -z "$findlast" ] && printf "Couldn't find last wan event in logs... exiting. \n" && exit 0   # nothing to calculate... exit

Wow, thanks guys! Weird that it isn't just sat there in the GUI like most other routers I've used!
