Probe for OMD and Nagios

"Probe for OMD" is an unofficial local agent. When installed over an android, it starts to provide data to network monitoring applications like OMD and check_mk.

This app can be installed over smartphones, tablets and IoT devices (like raspberry).

The app contains a service which can be started, stopped and launched at boot time. It listens over 6556 TCP port (configurable), replying to queries with data about :

- Battery: charge level, battery health, temperature and voltage

- Bluetooth: discovered devices and number of paired devices

- Cellular signal (GSM, UMTS, LTE)

- CPU: Statistics and load (user and system utilization), current frequencies.

- Available filesystems, their size and percentage of utilization

- Mounted partitions

- Kernel: number of context switches, page faults and process creations

-Inventory HW/SW (beta)

- Memory RAM : dimension and usage (swap, pagetables, mapped..)

- Number of threads

- Network Statistics: consumage of wifi and mobile data(last hour,day,month,year..)

- Sensors (Light, magnetic compass, accelerometer, gyroscope, ..)

- SIM Cards: information

- System time

- TCP Connections (Number of established,close_wait,time_wait,.. connections)

- Uptime

- Vmalloc address space

- Wifi: current wifi networks and neighbors networks

- size of user's folders (Downloads, Documents, DCIM, Music,..)

Now is possible to track signal strenth of all neighbours WiFi networks.

There are also experimental probes, usually disabled by default, providing data coming from sensors like light level, accelerometer, compass.

** NEW ** I've started to implement an NSCA agent, in order to submit directly passive check results to server, without to have to wait polling from server. This is useful in several scenario, for instance when device is not directly reachable from server (NATs, mobile connection..)

I'm adding new checks. Any feedback/suggestion/improvement is welcome. I'm also interested about your usage.

This app can have a significant impact over the battery charge, because the service uses a TCP server socket.

I want to thanks Mathias Kettner for his implementation of check_mk agent, from which I was inspired
