Broken Graph in Email Alerts

    Description

      We have an Alert Checker sending an email alert when a device is down/unreachable using the following test condition:

      device_status notequals 1

      The email alert generated contains a graph of "device_ping" referencing ping.rrd. This test condition has worked well for many years.

      However, if the device SNMP setting are set to "Skip ICMP echo checks, only SNMP availability.", no ping.rrd exists and the graph in the email alerts shows pink with "Error Drawing Graph". Clicking the broken graph reveals a message noting the missing ping.rrd file.

      Unfortunately ICMP is not available or relevant for all the devices we monitor due to NAT and port redirects required at some locations.

      Might be better to reference ping_snmp.rrd in cases where Ignore Ping is enabled?
