I am currently trying to clean-up my sitemap. I am using the network binding a lot to check if the online / offline state of my network. As a lot of network appliances have two network interfaces (LAN+Wifi or 2 x LAN) I often have two items for a device:
In my example I have for my NAS which has two ports the following items:
Switch F2_SR_NA_01_Eth0_ONOFF "NAS-01 Eth 0 [MAP(online.map):%s]" <onas> (F2_SR) Switch F2_SR_NA_01_Eth1_ONOFF "NAS-01 Eth 1 [MAP(online.map):%s]" <onas> (F2_SR)
The example above gives me both interfaces on my sitemap. But i would like the sitemap to show me one of the 4 options
offline if both Eth0 and Eth1 are not pingable
eth0 if only Eth0 is pingable
eth1 if only Eth1 is pingable
and eth1 + eth0 if both are pingable
I was actually hoping that I can tell the visibility function to check the state of two items. But that didn’t work.
Then I thought i could take a “detour” by converting the the state of the items with a MAP into a number and summing these up. So that Eth0=ON=10, Eth0=OFF=0, Eth1=ON=1, Eth1=OFF=0. In other words i can get values of 10,11,0,1. For this i created the following items
Switch F2_SR_NA_01_Eth0_Num "Test Eth0 [MAP(eth0.map):%s]" (Test, NA01) Switch F2_SR_NA_01_Eth1_Num "Test Eth1 [MAP(eth1.map):%s]" (Test, NA01) Group:Number:SUM NA01 "[%.0f]" (Test)
My problem is that item NA01 does not give me a sum of the two items.
Does anybody have an idea how to approach this problem. Or maybe even with a more elegant solution
