I want to save the number of connected users for each of my wireless interfaces using a script. However, it would seem I messed something up, because it’s not working.
Here is my code, I did some testing and it seems the code gets stuck in an infinite loop inside the “foreach”, on the “else” branch. For some reason, the file just doesn’t get created.
:global ifLastSaved
:local time [:pick [/system/clock/get time] 0 5]
:local day [:pick [/system/clock/get date] 4 6]
:local interfaces "12.1_5g,12.1_ch1,12.2_ch1,12.3_ch6,12.4_ch11,12.5_ch11"
:local ifArr [:toarray $interfaces]
#initialize save time
:if ([:len $ifLastSaved]=0) do={ :set $ifLastSaved [:pick $time 0 2]};
:foreach if in=$ifArr do={
:local data ($time." ".[:len [/caps-man registration-table find interface=$if]])
:local filename ("resziget/" . $if . "/" . $if . "-" . [:pick [/system/clock/get date] 4 6])
#we have to create a new file every few hours because of the 4096 character limit
:if ([:pick $time 0 2] > $ifLastSaved +2) do={
:set $ifLastSaved [:pick $time 0 2]
:set $filename ($filename . "-" . [:pick $time 0 2])
/file print file=$filename
:while ([:len [/file/find name=$filename]] = 0) do={ :delay 100ms }
/file set $filename contents=""
} else={
:set $filename ($filename . "-" . $ifLastSaved)
:if ([:len [/file/find name=$filename]] = 0) do={
/file print file=$filename
:while ([:len [/file/find name=$filename]] = 0) do={ :delay 100ms }
}
}
#this part returns "no such item"
/file set $filename contents=([get $filename contents] . $data)
};
If anyone could point out why this happens and how can I fix it, I would be really thankful. I’ve spent the last few hours testing and tweaking the code and I just can’t seem to make any progress.
Edit: I want to run a scheduler with this script. This script would iterate over my CAPs interfaces and extract the number of connected clients from each one. Then it would put the information in a file. We’d add new info at the end of the file for a while (3 hours currently), then we’d create a new file because of the 4096 character limit I heard about. For some reason, the file creation fails. The while-delay loops are supposed to prevent attempting to set a file before it is created. I tried without them, but that also doesn’t seem to work.
First step must be create a routine for everything, not only the cap, that create a file,
and backup the contents automatically before adding the new log line go over the max (that is 4095, not 4096).
On reboot is resumed last file.
If the device have Flash, not NAND, the file is created accordingly.
