  1. Information and Process Management Kevin Jacobson

  2. MDS4 • Part of the Globus Toolkit • Used for monitoring the status of the grid

  3. MDS4 as a Web Service • Collects data from: • Queuing Systems • Torque • PBS • LSF • Services • Cluster Monitoring • Nagios • Ganglia

  4. WebMDS • Web Front-end • Generates web content from MDS4’s WS • TeragridWebMDS • CURRENTLY THE SERVER IS DOWN! • Another Example • Campus Grid • http://iwrcggt4.fzk.de:8080/webmds/

  5. Food for Thought • Files in Linux are represented as files • Devices in Linux are represented as files • The state of the system represented as files?

  6. /proc • Part of the virtual filesystem • Contains information relating to the state of the system • Processes, CPU, Battery, Sensors

  7. /proc directory tree • File for every PID • /proc/uptime • System uptime • /proc/acpi/ • Files containing fans, battery, etc..

  8. Commands that utilize /proc • lspci • apm • free • top

  9. lspci • Reads from /proc/bus/pci • Provides a list of devices on PCI bus EXAMPLE:

  10. apm • If kernel supports apm • Returns status of the acpi • -s • Sleep the system • -S • Suspends the system

  11. free • Displays memory and swap usage on the current machine Example:$ free

  12. top Realtime system statistics

  13. Using top • Use arrows to select Processes • k to Kill • r to Renice • More commands • m to toggle memories • o to reorder columns • t toggle CPU and process stats

  14. The Windows Registry • A database of settings and options • Information ranging from startup settings to serial keys to the user theme • Consists of Hives (logical divisions) containing keys and subkeys which are organized in a directory-like structure. Within these subkeys are values

  15. Registry Hives • HKEY_CLASSES_ROOT • Information about file-associations and registered applications • HKEY_CURRENT_USER • Configuration information relating to the currently logged in user • HKEY_LOCAL_MACHINE • Contains service, Windows settings and driver information

  16. Hives … • HKEY_USERS • Contains the HKEY_CURRENT_USER settings for all users • HKEY_CURRENT_CONFIG • Information gathered at runtime not stored on the hard drive • HKEY_PERFORMANCE DATA • Hidden hive containing performance data about the system

  17. Regedit • A GUI browser for viewing and modifying the registry database • Double click on a value to modify • Right Click > New • Add a value in current “directory” • File > Export • Backup the entire system registry

  18. http://grid.rit.edu

  19. .REG file format [<Hive Name>\<Key Name>\<Subkey>] “Value Name”=<Value Type>:<Value Data> CMD: REG \s filename.reg

  20. In Conclusion • System status needs to be monitored • Various paradigms of doing so exists • Web services (MDS4) • File Systems (/proc) • Databases (Windows Registry)
