Check_MK Werk 6646: CPU utilization per process can be weighted by total CPU number

by Óscar Nájera

ID: 6646 Title: CPU utilization per process can be weighted by total CPU number Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Processes that where monitored on CPU utilization did not have a consistent behavior. On windows systems 100% CPU utilization implied all cores in the system where at max load. On other systems every core contributed with a 100% at full load, thus the maximum load was N*100%. This was also inconsistent with the system wide CPU utilization check where, 100% is all cores at full load. Consistency is brought is this werk, where 100% is all cores at full load by default. For backwards compatibility with previous configurations, where threshold rules were explicitly configured, the old behavior continues to be used until the user explicitly chooses a particular behavior. This option is available under CPU rescale maximum load in the process discovery rules.

Check_MK Werk 6849: Analyze configuration: Fixed wrong results for liveproxyd and persistent connection tests

by Lars Michelsen

ID: 6849 Title: Analyze configuration: Fixed wrong results for liveproxyd and persistent connection tests Component: WATO Level: 1 Class: Bug fix Version: 1.6.0i1 Previously all analyze configuration tests were executed locally on each site. In case of the liveproxyd tests and persistent connection tests this was wrong because the tests have to check the connection configuration for a specific site on the central site.

Check_MK Werk 6846: More secure password hashing

by Lars Michelsen

ID: 6846 Title: More secure password hashing Component: Multisite Level: 2 Class: Security fix Version: 1.6.0i1 Passwords of local users of the Check_MK GUI are now hashed using SHA256 (salted, 535000 rounds) to increase the security of the stored user logon passwords. All existing users will still be able to login using their already hashed passwords. Once a user changes his password or a new user is created, these will be hashed using the new algorithm. Why SHA256? Check_MK supports different authentication frontends for verifying the local credentials: a) basic authentication (done by apache) and b) the GUI form + cookie based authentication. The default is b). This option is toggled with the "omd config" option MULTISITE_COOKIE_AUTH. In case the basic authentication is chosen it is only possible to use hashing algorithms that are supported by apache which performs the authentication in this situation. For best compatibility in all mentioned situations we use the SHA256 scheme.

Check_MK Werk 6671: WATO Web API: Now able to configured rulesets with boolean settings

by Andreas Boesl

ID: 6671 Title: WATO Web API: Now able to configured rulesets with boolean settings Component: WATO Level: 1 Class: Bug fix Version: 1.6.0i1 Rules with a configurable positive/negative outcome where incorrectly translated in a <tt>get_ruleset</tt> API call. Furthermore, <tt>set_ruleset</tt> had an error when validating these kind of rules.

Check_MK Werk 5516: cmk-update-agent: Catch HTTPS redirect

by Andreas Umbreit

ID: 5516 Title: cmk-update-agent: Catch HTTPS redirect Component: agents Level: 1 Class: Bug fix Version: 1.6.0i1 A communication between the Agent Updater and the Check_MK-Server won't succeed if the communication protocol is configured to HTTP while the server enforces HTTPS. The reason is that the POST data sent by the Agent Updater will be lost on the redirect. So far, this is normal HTTP behavior. Nonetheless, the Agent Updater now handles this situation by detecting the redirect and directly sending its data via (unverified) HTTPS. A warning will therefore be displayed to the user respectively written to log.

Check_MK Werk 6645: Solaris Agent: Correctly separate cputime and elapsed time in agent info

by Óscar Nájera

ID: 6645 Title: Solaris Agent: Correctly separate cputime and elapsed time in agent info Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 The process information delivered by the agent has been upgrated multiple times by requirements of users or information available from the OS. The ps agent tracked the memory outilization of a process by its name, but could not access information of process id and the time of life(elapsed time) of a running process, as such information was misplaced by the agent and thus ignored by the check. This fix brings this data into consideration by the check.
