LM Article Larger Images Please

Better quality images are definitely needed there.

However, I recommend against extending snmp. It's messy, performance is not great, and requires stuff on the remote side to work. Better to use Expect or JSch scripted DSs. I've a couple of examples I can link when I get back to the office in a few minutes. 

Here you go: https://github.com/sweenig/lmcommunity/blob/master/PiJuice/collect.groovy

In this script, I compose the python script within my groovy script. Then the groovy script connects to the server via SSH, runs the script on the command line, grabs the output, then extracts the data from the returned json. 

//SETUP PORTION OMITTED (it's in the linked github repo)
pythonScript = """import json
from pijuice import PiJuice
x=PiJuice(1,0x14)
output = {}
output["charge"] = x.status.GetChargeLevel()
output["status"] = x.status.GetStatus()
output["temp"] = x.status.GetBatteryTemperature()
output["voltage"] = x.status.GetBatteryVoltage()
output["current"] = x.status.GetBatteryCurrent()
output["iovoltage"] = x.status.GetIoVoltage()
output["iocurrent"] = x.status.GetIoCurrent()
print(json.dumps(output))
"""

power_input_status = ["NOT_PRESENT": 0, "BAD": 1, "WEAK": 2, "PRESENT": 3]
battery_status = ["NORMAL": 0, "CHARGING_FROM_IN": 1, "CHARGING_FROM_5V_IO": 2, "NOT_PRESENT": 3]

try {
  def userCmd = getCommandOutput("python3 -c \"${pythonScript.replaceAll("\"","'").replaceAll("\n",";")}\"")
  data = new JsonSlurper().parseText(userCmd)
  println("5v_power_input_status: ${power_input_status[data.status.data.powerInput5vIo]}")
  println("charge: ${data.charge.data}")
  println("battery_status: ${battery_status[data.status.data.battery]}")
  println("power_input_status: ${power_input_status[data.status.data.powerInput]}")
  return 0
}
catch (Exception e) {println "Unexpected Exception : " + e; return 1}

Hi Stu, if we don't have an ssh user/pass then we need to still use the old method?
What's a simple OOTB snmp DS that I can use to clone, change the OID to poll to create this custom DS? Its for monitoring MISP jobs status?

Here's one i did long ago. I recently rebuilt it to be an SSH based DS, which is also in that repo.
