PHP Server Monitor is a script that checks whether the servers/Websites on your list are running. Each server has its own notification settings. Notifications are made via email or text messages. Using the Web-based interface, you can add servers and manage users for each server.
STOR2RRD provides storage performance and capacity monitoring for IBM DS8000, IBM Storwize, and IBM SVC. It generates historical, future trends, and nearly "realtime" performance utilization graphs of monitored storages. It graphically presents the IO rate, data throughput, and response times for all Ports, Pools, Ranks, Mdisks, Volumes (LUNs), and drives. It collects complete physical and logical configuration of all storages.
Upsilon is a distributed, flexible, and extensible system monitoring application. Being distributed means you run service checks on Upsilon nodes in your network where it makes sense, either on every server or on a management network, inside or outside the firewall. You can run checks on secure, hard to reach networks, and push those results to a central server. You can optionally execute "agentless" checks just by using SSH. Being flexible means that if you can script it, you can monitor it. Unlike most monitoring systems, the monitoring scripts are external to the main server, so you can use Upsilon to execute your monitoring scripts in an extremely robust way. Upsilon has been used to monitor many different things and is API-compatible with all nagios monitoring scripts. Being extensible means you can add monitoring checks to Upsilon at runtime without needing to restart the server. The upsilon-node and upsilon-web projects both have their own REST APIs.
nxgipd is a monitoring daemon for UTC / GE Interlogix / Caddx alarm systems that use the Networx NX-584 protocol. Supported alarm systems and panels include the NX-8, NX-8V2, and NX-8E. The daemon process requires minimal memory and CPU resources. It continuously monitors the alarm panel and logs any activity into local log file and/or to syslog. The nxstat program can be used to query panel status in real-time. It typically requires a NX-584E (home automation) module or for the built-in serial port to be enabled (NX-8E panel).
aerotools-ng provides a C interface for accessing the Aquaero5 USB device by Aqua Computer. It consists of a set of functions for data access and conversion, and a commandline tool using these functions as an example implementation. It also includes utilities for exporting sensor data to SNMP to be used by NMS and other monitoring/graphing tools.
vded is a simple REST-type method for tracking deltas of ever-increasing values (although it handles resets, etc., pretty well). It is meant to accept submissions of values which increment, then determine the delta between that value and its predecessor, as well as figure the rate over time.
