zTCP is a Simple Network Management Protocol (SNMP) client that runs on z/VM and measures the performance of Linux hosts and applications running almost anywhwere.

It runs in a service machine that writes performance data received from SNMP to the standard VM monitor data stream. The zMON and zMAP machines then process the data.

To manage multiple TCP/IP networks, IP addresses, physical network connections and security, authorizations are required.

zLMD is a new z/VM-centric capability from Velocity Software that supports secure data transfer and can serve as a replacement for using SNMP with zTCP when stricter security protocols are required.
See the README file for zLMD in your customer download area for more information and installation instructions.

Features and Benefits:

• zTCP can measure any SNMP-compliant host or application - including z/VM, Linux, Windows and most Unix networks.
• zTCP collects a vast amount of information including: connection times, client performance data and TCPIP layer data.
• zTCP also collects application data. This includes MongoDB, Oracle, Docker and GPFS via a Velocity provided MIB.
• zTCP can also monitor VSE systems using the supplied SNMP function that shows system related data. Velocity provides a plugin that also shows partition (job) information.
