again there has been a bug in the OID in the check fortigate_sessions. Or maybe I didn’t create the package carefully enough. Anyway there is a new version 2.2.2 and it’s located as always on the check_mk exchange site. Please consider updating as soon as possible, because the version 2.2.1 collects wrong values.
Best regards
Hermann Maurer
I hope you enjoy the great monitoring software Check_MK. If you have a big environment with lots of hosts and services distributed over dozen of sites (company locations) , you might have already configured your Check_MK to use the distributed monitoring in WATO. I assume that you have got a master and some slaves. The master in terms of Check_MK is the host, which you are using to configure your whole Check_MK installation and to look at all hosts and services, whilst slaves are those hosts that receive the configuration from the master and which the master gets the monitoring results from. Distributed monitoring is an extremely nice and powerful feature of Check_MK that allows you to keep your configuration at one place and that takes care on distributing the changes on the configuration to the slaves. Also it’s very easy to connect a new slave to the master site.
Ссылка на статью, которая занимается конечно же, украинскими событиями, но не только. Сильный текст, показывающий, что такой чувствующий человек, как драматург Е.Гришковец мнгогое переживает внутри себя, со многим происходящим вокруг него не согласен, что его многое ранит. Далеко не все утверждения автора я я разделяю. Некоторые мысли у него заметно эмоциональны, вызваны, может быть, обидой. Но тем не менее меня подкупает искренность автора и его отчётливое понимание, что его собственные ощущения очень субъективны и личны, и что он не присваивает себе право на абсолютную правоту.
I’ve just uploaded a new version of the check to Check_MK Exchange site. This is a bug fixing version, is doesn’t contain any new features.
The new version includes a minor bug fix in fortigate_sslvpn check. I corrected the OID used there to get the value of the active SSL VPN sessions. The old versions might show a wrong number of active sessions. Please update the package.
In some distributed environments and with a lot of configured users and connection to Microsoft active directory configured in Check_MK times to distribute the changes from the master to all slave sites grow up strongly. Check_MK distributed monitoring uses Apache web server acting as reverse proxy. Sometimes one of Apache web server’s instances doesn’t return data within a pre-defined time range. In such cases you can get the error like this while trying to replicate your slave with the master site:
If you’ve got a fresh Fortigate and want to configure it as HA, you have to prepare something, because the factory-standard configuration doesn’t let you to enabled High Availability.
The preparation steps are as follows:

I shot the image while staying on the new bridge in Frankfurt named "Osthafenbrücke". The large house at left side of the picture is one of designed and built by a very famous Austrian architecture F.Hundertwasser.I had to configure OMD/Check_MK version 1.2.4p3 to use LDAPS to connect to Windows domain controller. The operating system on the host running OMD/Check_MK is CentOS 6.5 x64.
Assume the following scenario:
Your Postfix MTA is located in the Internet (having a public IP address) and you have configured an external DNS server there to be used for DNS requests. But you are going to send mails using an internal mail server as mail relay. In this case the private IP address of the internal mail relay cannot be re-solved by the external DNS server. In this situation Postfix cannot use the mail relay and shows an error message like this below in the log file:
Aug 26 12:49:12 myclient postfix/error[28425]: B35AF34B: to=<me@company.local>, relay=none, delay=0.14, delays=0.09/0/0/0.04, dsn=4.3.5, status=deferred (delivery temporarily suspended: Host or domain name not found. Name service error for name=mailrelay.company.local type=AAAA: Host not found)
To re-solve the issue you have to add the following statement to main.cf
disable_dns_lookups = yes
and re-load postfix:
service postfix reload
Use the appropriate command to enforce delivery of queued mails.
