Create channels from custom SNMP query

Hello,

I'm afraid it's not possible to convert the string to different channels. You can however create a sensor for each value and extract each value using RegEx within the sensor settings using the SNMP Custom String Sensor. You can also choose "interpret result as Bytes in hexadecimal notation" here.

But with approach where I create five sensors to handle single data string (which by the way makes automaticly lot's of more money to Paessler...) I have to do five queries to device to get same value and that does not make sense to me to torture device with many "useless" queries.

Another thing what I do not understand is that how can I use extracted value as a Primary channel value instead of Response time? Every way I try to get it as value of graphic display I still get milliseconds... I can get value visible in gauge with priority setting but value is still response time's milliseconds.

Generally, you can use the SNMP Custom Advanced sensor to monitor multiple different values in multiple channels in just one single sensor. However for each value you need to enter one single OID.

Usually in most SNMP implementations a device should only return one specific value for one OID. This is what the SNMP sensors are built for. Returning multiple values or a "data string" within just one single OID is not really common. Also, I wouldn't say "torturing" the device, since SNMP hardly have any performance impact as long as you're not using SNMPv3.

Are you able to extract the value correctly in one channel? You can then change the primary channel using the "pin"-symbol. Also have a look here: https://www.paessler.com/manuals/prtg/sensor_channels_settings. Feel also free to send us screenshots to [email protected] if you want us to take a closer look.

Well I'm talking about Korean display manufacturers snmp implementation so everything is possible.

In my snmp custom sensor there is only two channels: Downtime and Response Time and only place I can see extracted value of sensor is on top row of sensor (the part which is green/yellow/red and has name of sensor) I have sawn messages where there is also third channel which has sensor value but I do not have such channel available?!? I will send image to support whith this same text so you can see my problem.
