Check_MK Werk 8118: Smartping: Fixed "no buffer space available" error when having a lot of hosts configured

by Lars Michelsen

ID: 8118 Title: Smartping: Fixed "no buffer space available" error when having a lot of hosts configured Component: cmc Level: 2 Class: Bug fix Version: 1.2.7i1 We already changed the way smartping was operating some time ago, this solved the "no buffer space available" problem for many systems and increased the possible number of hosts to be pinged dramatically. This did not fix the problem for all systems. Some systems with maybe slower network cards or drivers still had the problem that the message "no buffer space available" appeared from time to time in the cmc.log. This occured when the cmc was asking for ping requests faster than the kernel / NIC could process them. The send queue of the single raw socket was filling up to the maximum and then resulting in this error message. The icmpsender now opens 8 sockets instead of 1 for sending the ICMP requests. Additionally the socktes now get a larger send buffer to make it less likely to fill up.

Check_MK Werk 8113: Timeouts are now handled like classic SNMP implementation

by Lars Michelsen

ID: 8113 Title: Timeouts are now handled like classic SNMP implementation Component: inline-snmp Level: 2 Class: Bug fix Version: 1.2.6b1 Timeouts of walks/bulkwalks of Inline-SNMP are now handled equal to classic SNMP implementation. When a timeout occurs for the configured X SNMP retries after Y SNMP timeouts (configured via SNMP Timing Options), the whole "Check_MK" service is terminated assuming that the host is not available.

ID: 8115 Title: Suggesting "time" package, used for mk-job, in debian packages Component: agents Level: 1 Class: Bug fix Version: 1.2.6b1 When not present, mkjob simply does not work. So if you like to use mk-job, you need to have the "time" command available, which is packaged in the "time" package on debain systems.
