using one graph template, same data is being shown in different devices

[houtaro]

Bug description:

Server 1 disk usage: 20%
Server 2 disk usage: 14%

Created a custom bash script to get disk usage of a Linux server. Created a graph template using the bash script, then created 2 devices (Server 1 and Server 2) with the same graph template. Upon checking the disk usage of the 2 devices, they have the same value: 20%.

Steps to reproduce:

1. Create a Data Input Method using the bash script to get disk usage of a Linux server.
2. Create a Data Source using the Data Input Method created in Step 1.
3. Create a Graph Template using the Data Source created in Step 2.
4. Create 2 devices.
5. Assign the Graph Template created on Step 3 to the 2 devices created in Step 4. (This will create a graph for each device. e.g. "Server 1 - Disk usage", "Server 2 - Disk usage")
6. Create 2 Trees.
7. Add the 2 graphs (generated on Step 5) to the appropriate trees.
8. Check the value of the graphs.

Expected behavior

I'm not quite sure how Cacti uses the custom script I created, but I think Cacti will execute the script on Server 1 and graph the result, then execute the script on Server 2, then graph the result. Thus, the 2 graphs should have different results.

Yea I reported something similar to this are you using multiple poller? For me it's cacti stats showing the same info for all my pollers

I only have 1 poller, but I have 2 devices, and the graphs for those 2 devices are displaying the same value

A "bash script" will only ever be executed on the Cacti server. It isn't going to copy it over to any server and execute it. That is not how Cacti works.

You should instead be using SNMP data to get Disk Space graphs on Linux/

Oh, right. I thought the bash script will be executed on multiple servers. Thanks for the clarification!
