Monitor several paths for new files

[aratom]

Hey there!

I'm wondering how I could optimize my system. I'm monitoring several paths on different servers where different application export data or write a backup. Basically if I there has been no new file within 24 hours Zabbix notifies me and I know that some system failed.

I already have a template with an item setup successfully. My key is vfs.dir.count[{$PATH},{$REG_INCL},{$REG_EXCL},{$TYPES_INCL},{$TY PES_EXCL},{$MAX_DEPTH},{$SIZE_MIN},{$SIZE_MAX},{$A GE_MIN},{$AGE_MAX},{$REG_EXCL_DIR}]. On the host I can specify the desired macro values.

Trigger is last(item)<=0 and recovery last(item)>0 for the item.

Until now I was very satisfied with my setup. Now I was wondering how could I improve my setup to e.g. monitor two paths on one server. Of course the exporting software could notify me over mail, Zabbix send, log file, Windows events, ... but I cannot change the software code because I don't have the source code and the developers stopped supporting this product.

I thought a lot about how to implement this. My only idea was to create an item directly one the host for each file to monitor.

I'm sure there would be a better way to implement this.

If anything is unclear, I can try to improve my explanation.

Thank you!

I will briefly describe the solution path (for details, go to the documentation): Create an LLD rule of the script type (in the script field, create a json containing a list of directories to track) which creates items from this json. https://www.zabbix.com/documentation...evel_discovery
Hint: in the script, you can simply output the value of the macro, and write json to the macro.

thank you Hamardaban!

I was able to get my basic setup working with your guidance.
It was not easy to setup. Mostly because I didn't know how to work with macros and JavaScript. According to my research the official documentation has no example on this. So for future reference, hopefully it helps someone

I created a template with a discovery rule of type script

var macro = '{$PATHS}';
var array = macro.split(',');
var obj = [];

for(var i = 0; i < array.length; i++){
    obj.push({"{#PATH}": array[i]})
}

return JSON.stringify(obj);​

Also I was not able to use forEach. Maybe it is my fault. I found no documentation on which functions are available.

My item prototype uses the following key

vfs.dir.count[{#PATH},{$REG_INCL},{$REG_EXCL},{$TYPES_INCL},{$TYPES_EXCL},{$MAX_DEPTH},{$SIZE_MIN},{$SIZE_MAX},{$AGE_MIN},{$AGE_MAX},{$REG_EXCL_DIR}]

On the host I can define all the macros.

Most important macro is {$PATHS}. It can be populated with encoded paths (\\ instead of \) like C:\\Windows,C:\\temp
Several paths can be separated with comma

Have fun!

I'm glad for you that everything worked out.
