PDM: Programmable Monitoring For Distributed Applications
نویسندگان
چکیده
We have constructed PDM, a Programmable, Distributed Monitoring system for building performance monitoring/analysis, steering, and adaptive systems for largescale, parallel applications. PDM takes advantage of mobile languages to reduce monitoring overheads and offers new monitoring capabilities. PDM monitoring code is currently written in Tcl. PDM is capable of decomposing and distributing the monitoring code to the nodes in the system where the performance data is generated, thereby reducing the amount of network traffic required to collect monitoring information. Furthermore, PDM scripts can monitor and bound their own resource usage, further reducing monitoring overheads.
