HTTP Push Data Advanced does not reliably display the "Last Value"

Last Value is always the latest value received within the sensor. Is this your actual output, because <valuevalue> is not correct - but I assume it's a copy/paste error?

Gah! Yes, that's a copy/past from my SSH terminal issue.

Here's the actual line (edited for privacy): curl "http://blah-blah-blah:5050/1l?content=<prtg><result><channel>IP-Octet-1</channel><value>10</value></result></prtg>"

Thanks, Doug

I am personally using this sensor pretty happy in a different use case with counters and other values like temp and humidity and time-differences.

In the end we talk about multiple of those sensors, all with multiple channels.

No issues at all - proven by various graphics and data validation that we did on this.

Not sure what is going on exactly in your case - but it might help if you can post the script you are using or as mention re-validate the output - e.g. <valuevalue>...

Hopefully we can sort it out and find a working solution for you!

I'm using the HTTP Push Sensor to capture the IP address of Raspberry Pi units on my network that are also HTTP Pushing Temp/Humidity/Pressure data. The units are set for DHCP and therefore I don't know what their IP address will be. Given the number of units and the varied network environments I must use DHCP. This script runs in /etc/rc.local and should push the IP address in four separate values. (Don't ask what will happen when we get to IPv6!)

#!/bin/bash

mac_col=$(cat /sys/class/net/$(ip route show default | awk '/default/ {print $5}')/address)

#echo $mac_col

mac_dash=${mac_col//:/-}

#echo $mac_dash

mac_dash_all="$mac_dash-ip"

#echo $mac_dash_all

#exit
while true; do

	#Public IP
	#ip=$(curl -s https://api.ipify.org)

	#Private IP
	ip=$(/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}')

	oct1=$(echo ${ip} | tr "." " " | awk '{ print $1 }')
	oct2=$(echo ${ip} | tr "." " " | awk '{ print $2 }')
	oct3=$(echo ${ip} | tr "." " " | awk '{ print $3 }')
	oct4=$(echo ${ip} | tr "." " " | awk '{ print $4 }')

        echo $mac_dash_all

	echo $ip
        echo $oct1
	echo $oct2
	echo $oct3
	echo $oct4

        curl "http://blah.blah.blah.com:5050/$mac_dash_all?content=<prtg><result><channel>IP-Octet-1</channel><value>$oct1</value></result></prtg>"
	sleep 1

        curl "http://blah.blah.blah.com:5050/$mac_dash_all?content=<prtg><result><channel>IP-Octet-2</channel><value>$oct2</value></result></prtg>"
	sleep 1

        curl "http://blah.blah.blah.com:5050/$mac_dash_all?content=<prtg><result><channel>IP-Octet-3</channel><value>$oct3</value></result></prtg>"
	sleep 1

        curl "http://blah.blah.blah.com:5050/$mac_dash_all?content=<prtg><result><channel>IP-Octet-4</channel><value>$oct4</value></result></prtg>"
        sleep 5

done

When the sensor is setup and I run the script manually once (before it's looping and running automatically) I can see that all four values are being reported to PRTG because I can see all four values in the "Maximum" column of the sensor. Even though the "Last Value" column will often report only one of the four values. Which of the four seems random.

Thanks, Doug

PS I've tried to edit the original question SEVERAL times (to correct my type-o) from different PCs and each time I click submit I get kicked to the error screen with the guy dabbing and my edits are gone. Just an FYI.

Florian,

That did the trick and not only did that work, but I didn't know that you could put multiple values in one push.

Thanks!

Doug

You can put even more in that.. there are various ways to transfer the data as well and you could determine stuff like limits and even pass through a text-string (not per channel, only one per probe) etc..

Glad it worked :-)

Florian

As always, thanks for the help! :)
