You have probably already tried configuring a "Plain text" screen element. Indeed, there it shows the number of seconds (14756237) instead of the value being formatted as uptime (170 days, 18:57:17). The same issue is when viewing "Values" and "500 latest values" in "Latest data". There are two workarounds that seem to be available: configure "Simple ...

For any people still wondering, unsupported item notification is now supported since Zabbix 2.2 and involves creating a specific Action (not an Item), and include all details concerning the unsupported item in the notification. The complete procedure is described in the Zabbix official documentation.

In your hostapd.conf: # Module bitfield (ORed bitfield of modules that will be logged; -1 = all # modules): # bit 0 (1) = IEEE 802.11 # bit 1 (2) = IEEE 802.1X # bit 2 (4) = RADIUS # bit 3 (8) = WPA # bit 4 (16) = driver interface # bit 5 (32) = IAPP # bit 6 (64) = MLME # # Levels (minimum value for logged events): # 0 = verbose debugging # 1 = debugging ...

Usually you can track events from access point(s) by checking its logs. Some of the APs support syslog export, so you can direct AP's logs to your local system and use something like fail2ban or other log analyzer to catch failed attempts. Not all APs support exporting logs with syslog. Edit: It seems to be possible to sniff for the traffic, once you're ...

Look into Cacti, it has a wide range of devices it supports. The initial set up is a little tricky but it will do just about anything you can imagine afterwards.

I've seen recently a response on spiceworks website so I'll quote it. tools like treesize cannot help me finding what folder growed since yesterday ? I am talking about a file server with thousands of folders and files (380GB data) I use xinorbis (freeware) by now but it needs 6 hours to scan our file server with 386Gb of data while it runs as ...

The reason you're getting this error is that Zabbix is trying to look for an agent on 103.7.200.87 to connect to. You'll want to use a simple check (icmpping)if you're just trying to ping a server without an agent. https://www.zabbix.com/documentation/2.0/manual/config/items/itemtypes/simple_checks

made it work with this nginx config file: location ^~ /hobbit { alias /usr/lib/hobbit/server/www/ ; index index.html ; } location /cgi-bin/ { alias /usr/lib/hobbit/cgi-bin/; } location /cgi-secure/ { alias /usr/lib/hobbit/cgi-secure/ ; }

This is old, I know, but monit has a basic API, found at "http:SERVER_IP:2812/_status?format=xml" There also appears to be a JSON format as well (change format to json from XML). You can parse the XML for everything you need (I've done it in python easily). However, I can't seem to find any documentation on this, so you have to discover what you can. ...

LVS (which uses ipvsadm as a cli) and HAProxy both sit at the same functional load balancing layer. You would generally use one or the other, but not both. HAProxy has the web stats ui which looks like this: You can also access the stats via a csv file. A github repo has a ganglia gmetric script you can use to graph the data. The LVS documentation ...

Well, I would start off with the naive approach like so: $ top |grep %pid On ubuntu 12.04, it outputs the line for the PID once per update of top: username@usrver / $ top |grep 2593 2593 username 20 0 1103m 170m 16m S 30 2.2 67:25.38 chrome 2593 username 20 0 1103m 170m 16m S 28 2.2 67:26.24 chrome 2593 ...

Go to Home / Search / Node List and select the specific Node you have a problem with. In the Node Management page goto Admin > Manage and Unmanage Interfaces and Services. Deselect the service you wish unmanaged and click Apply Changes. In the availability view of the node the SMTP service should now read something like "Forced Unmanaged".

incrond (inotify cron daemon) behaves like cron but uses inotify as the triggering mechanism. This guide has some pretty comprehensive examples. An example incron entry for the case you described might be: /path/to/file IN_CLOSE_WRITE /path/to/your_script

If you are running Linux, as I assume you are, then you can rely on Linux inotify mechanism that notifies user-space processes when files change. LSyncd is one program built around that feature, which you can configure to execute arbitrary commands when files change.

Check to see that the logs per second at your final endpoint (e.g. elasticsearch) are above some baseline. That is, do an end to end check, if your end result is working correctly, you know that all the steps in the pipeline work correctly. If you frequently have problems, or need better introspection, start instrumenting each piece of the pipeline like ...

I'm not aware of a plugin that can already do this. 30 seconds on google didn't yield anything either. There's a category of plugins for similar purposes on Nagios Exchange, but nothing that matches exactly what you need. You'll probably have to write it yourself. A simple bash script to look at the output of getfacl /path/to/my_file and/or stat ...

For those (Renan) interested to know what solution I came up with. I've been using a custom bash script to retrieve the memory (Used / Total) and then converting it to a percentage. #!/bin/bash ...

I have another way to achieve this, If you have have several things to upgrade on each server. That'll be very wasting to update 5 server for the same operations. Create a Load Balancing & Scaling Group.Ensure the connection draining is enabled. There's my upgrade step. Remove 1 instance from your load balancer. Update everything you need. And ...
