I am trying to add a calculated item based on a web scenario response time. I am trying to add an item like so:

avg("web.test.time[fut_perf,index,resp]", #5)+avg("web.test.time[fut_perf,about,resp]" #5)

I am hoping to get the combined value of both averages over 5 polls. I am getting the error:

ERROR: Page received incorrect data

    Warning. Incorrect value for [Formula]

I have also tried:

avg("web.test.time[fut_perf,index,resp]", 120)+avg("web.test.time[fut_perf,about,resp]" 120)
avg("web.test.time[fut_perf,index,resp]", 120)
avg(web.test.time[fut_perf,index,resp], 120)+avg(web.test.time[fut_perf,about,resp] 120)
avg(web.test.time[fut_perf,index,resp], 120)

Zabbix version is 1.8.4. Any ideas what I might be doing wrong? Is it possible that web scenario items are not supported in calculated items?

Have you researched the Zabbix forums? – Red Tux May 24 '11 at 3:18
Also what errors are you seeing in the zabbix_server.log file? You may need to increase the debug level to 4 in order to see something useful, but if you go that route you may also need to increase the log file size as well. – Red Tux May 24 '11 at 3:24

One thing that stands out is you're missing a comma in the 2nd average:

Actually, I am an idiot. I didn't realize there was a Formula textbox. I was entering this into the Key. My first example does work as desired (with the missing comma of course). I was getting frustrated on this and jumped the gun!
