It is built on top of the DTrace tracing framework from OpenSolaris, which was ported to Mac OS X v10.5 and which is available in all following versions of macOS. Instruments shows a time line displaying any event occurring in the application, such as CPU activity variation, memory allocation, and network and file activity, together with graphs ...
arpwatch is a computer software tool for monitoring Address Resolution Protocol traffic on a computer network. [1] It generates a log of observed pairing of IP addresses with MAC addresses along with a timestamp when the pairing appeared on the network. It also has the option of sending an email to an administrator when a pairing changes or is ...
[44] [45] Activity Monitor appeared in Mac OS X v10.3, when it subsumed the functionality of the programs Process Viewer (a task manager) and CPU Monitor found in the previous version of OS X. [46] [47] In OS X 10.9, Activity Monitor was significantly revamped and gained a fifth tab for "energy" (in addition to CPU, memory, disk, and network). [48]
Monitor Resource Usage: Use built-in system monitoring tools or third-party software to track CPU, memory, disk and network usage, and identify resource-intensive processes that may be slowing ...
The dialog also allows the user to restrict the parameters of the connection, for example allowing a given application to only connect to a certain domain or using a specific protocol or port. Little Snitch's integral network monitor shows ongoing traffic in real time with domain names and traffic direction.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
A common usage is to monitor network traffic by polling a network switch or router interface via Simple Network Management Protocol (SNMP). The Cacti end user front end supports both User and User Groups security models and supports Role Based Access Control (RBAC) for access to not only monitoring data, but various areas of the user interface.
Performance Co-Pilot (also known as PCP) is an open source software infrastructure for monitoring, visualizing, recording, responding to, and controlling the status, activity, and performance of networks, computers, applications, and servers.
