Big Sister 0.98 beta 4 Release NotesIn 0.98b4 we concentrated mainly on getting rid of a few nasty quirks and bugs. 0.98b4 should be smoother in setup and operation. RedHat 9 / Apache 2.0. A tiny but annoying incompatibility of the CGIs with Apache 2.0 has been fixed, Big Sister outputs a warning when running under certain Perl versions with UTF-8 support configured. The new style sensor concept is now stable. Please use new style sensors in uxmon-net (see NEWAGENT) wherever this is appropriate. The old-style tests will be deprecated one by one within the next few releases. New monitors. In order to prove that the new style sensoring stuff is of any use a few more monitors have been added, such as the networking monitor for Linux, the vmstat monitor that does CPU load reporting on systems without a SystemV sar. Remember that you can get an up-to-date list of available new-style sensors using the "testers" command. Image map creation has undergone some bug hunting. It's much more robust, now and configuration mistakes do not lead to bsmon shutdowns any more. Image map. The "at" and "line" statements now also accept host.check or group.check addressing. So you can display individual checks on image maps, too. Graphing. Virtually all of the new-style sensors support graphing. Therefore we get some really nice performance graphs now. The graph index pages now let you select multiple graphs to show up on the same page allowing us to easily compare various system performance variables visually. Inverse tests. New-style tests can be negated/inversed. For instance you can ensure that a host is not responding to SMTP requests via "myserver service=smtp !tcp" in uxmon-net. Network test speed override. Some systems (including namely Linux) do not provide correct interface speeds. You can now manually set interface speed for the "network" test, e.g. "myserver interface=eth0 speed=100Mb/s network". Test/host removing. Yet another step in the history of purple/host removing - the "bsadmin remove" and "bsadmin leave" commands should now work correctly under all circumstances. bb_event_generator.cfg. Fixed a few bugs in pattern matching code, should now work correctly with mixed case host names, too. Graphing. Adding/removing services or devices (such as e.g. mounting a new partition) makes Big Sister re-order things internally. The grapher now re-associates re-ordered performance values correctly so that the risk of Big Sister e.g. reporting free space of partition A with legend "Partition B" has gone. RPM. Got bsadmin back into the RPMs bsadmin. Accepts "enable"/"disable" commands for setting hosts into maintenance mode from command line. Name spaces. For developers: Everything has been moved out of the main:: namespace so that BigSister modules do not conflict with 3rd party software use-ing them. |
