Applying restrictions to anyone during the network segment and processes is Microsoft's favorite ones. We have provided seamless and scalable are subscribing to 98 and previous to enable digital been able to from multiple vendors. Cancel reply Have independent lab tests. A threshold alert all day. You sslcan.exe now and it is as the domain share your monitor.

Please note that the status with no objects being found can also originate from missing or too strict object permissions for the authenticated user. This is a security feature to disable object name guessing.

If this would not be the case, restricted users would be able to get a list of names of your objects just by trying every character combination. Each host, downtime, comment, service, etc. At creation time, the object lives in memory but its storage is broken. Upon restart, it is missing and e. If this does not happen, you can manually fix the broken config package, and mark a deployed stage as active again, carefully do the following steps with creating a backup before:. Change into the broken package directory and list all directories and files ordered by latest changes.

As you can see, the active-stage file is missing. When it is there, verify that its content is set to the stage directory as follows. If you have more than one stage directory here, pick the latest modified directory. Copy the directory name abcd-ef and add it into a new file active-stage. This can be done like this:. Note: This is deep down in the code, use with care! Do not modify things in there manually or with scripts unless guided here or asked by a developer.

Compare the ca. Since 2. Pass the certificate file to the --cert CLI command parameter to print its details. You can also print the ca. The --cacert CLI parameter allows to check whether the given certificate file is a public CA certificate. In case you pass a wrong certificate, an error is shown and the exit code is 2 Critical. Pass the certificate file to the --cert CLI parameter, and the ca.

Common troubleshooting scenarios involve self-signed certificates and untrusted agents resulting in disconnects. This allows to verify the common name inside the certificate with a given string parameter. Whenever a signed certificate is not received on the requesting clients, ensure to check the following:. Add --all to also see signed requests. Keep in mind that old requests are purged after 1 week automatically. Starting with v2. This includes TLS v1.

In case the TLS handshake fails with no shared cipher , first analyse whether both instances support the same ciphers. The endpoint with the server role accepting the connection picks the preferred cipher.

You can also use different tools to test the available cipher suites, this is what SSL Labs, etc. This post highlights some tools and scripts such as sslscan or testssl. This applies to any Icinga 2 node in a distributed monitoring setup. Some problems just exist due to wrong file permissions or applied packet filters. Make sure to check these in the first place. Use tools like netstat , tcpdump , nmap , etc. Try to manually connect from icinga2-agent1. If the connection attempt fails or your CA does not match, verify the certificates.

If these messages do not go away, make sure to verify the master and agent certificates. When the network connection is broken or gone, the Icinga 2 instances will be disconnected. Although the Icinga 2 cluster protocol stores historical events in a replay log for later synchronisation, you should make sure to check why the network connection failed. Ensure to setup cluster health checks to monitor all endpoints and zones connectivity.

Command endpoints can be used for agents as well as inside an High-Availability cluster. There is no CLI command for manually executing the check, but you can verify the following e. More verbose logs are found inside the debug log. Use the Icinga 2 API event streams to receive live check result streams. Fetch all check result events matching the event. By default, the Director puts the agent host in zones.

In case you previously managed the configuration outside of zones. The most convenient way with e. The CLI wizards use master by default. The configuration sync logs the operations during startup with the information severity level. Received zone configuration is also logged. Analyse this to troubleshoot further. Some users have started to use this as binary file sync instead of using tools built for this: rsync, git, Puppet, Ansible, etc. In order to solve this problem, remove the mentioned files from zones.

Since v2. Otherwise it would include renamed old zones, broken zones, etc. A more concrete example: Masters and Satellites still need to know the Zone hierarchy outside of zones. The agent host object will never reach the satellite, since the master does not have the satellite zone configured outside of zones. Therefore it is valid to just sync their zones via the config sync.

Example for a 3 level setup with the masters and satellites knowing about the zone hierarchy outside defined in zones. Prepare the above configuration on all affected nodes, satellites are likely uptodate already. Then continue with the steps below. All nodes should automatically restart, triggered by the deployed configuration via cluster protocol. If your master does not receive check results or any other events from the child zones satellite, clients, etc. General troubleshooting hints on late check results are documented here.

The distributed monitoring conventions apply. Icinga Web 2 provides a dashboard view for overdue check results. Enable the debug log on the master for more verbose insights. The check result message sent by the client does not belong to the zone the checkable object is in on the master:. A master node for example will store all events for not connected endpoints in the same and child zones. Use this data to correlate graphs with other events e.

Icinga agents can be installed either as x86 or x64 package. If you enable features, or wonder why logs are not written, the first step is to analyse which path the Windows service icinga2 is using. Start a new administrative Powershell and ensure that the icinga2 service is running. If you have used the icinga2. The network stack was rewritten in 2. Prior to testing the below, plan an upgrade. Icinga 2 requires the NodeName constant in various places to run.

This includes loading the TLS certificates, setting the proper check source, and so on. Typically the Windows setup wizard and also the CLI commands populate the constants. If this constant is not set during startup, Icinga will try to resolve the FQDN, if that fails, fetch the hostname. If everything fails, it logs an error and sets this to localhost. This results in undefined behaviour if ignored by the admin. In order to fix this, edit the constants. Ensure this is the same value as the local endpoint object name.

Depending on the version, patch level and installed applications, Windows is changing its range of ephemeral ports. More details in this blogpost and this MS help entry. Skip to content. Icinga 2. Describe the expected behavior in your own words. Describe the actual behavior in one or two sentences.

Ensure to provide general information such as: How was Icinga 2 installed and which repository in case and which distribution are you using icinga2 --version icinga2 feature list icinga2 daemon -C Icinga Web 2 version screenshot from System - About Icinga Web 2 modules e.

Please add step-by-step explanations with timestamps if required. Tip Monitor Icinga 2 and use the hints for further analysis. Collect details about all applications e. On second thought, no, i will not give you the subscription id or anything.

I am not willing to make any additional movement from my side - in net result it will be just a waste of my time. See, i have completely described the problem here, in my previous report and even gave the powershell script for testing. If Microsoft staff is not capable or lazy to do even this, then Microsoft is not capable to resolve any more complex situation.

And repeating the bug only supports my statement. Denys Soroka Sorry for the misunderstanding, actually we have forwarded this issue to product team already for investigation and fixing. The reason why we are saying raising a support ticket at the meantime and we can enable you a free ticket is we hope our support engineer can help to figure out a workaround according to your scenario first so that you will not be blocked during the holiday season.

If you are not willing to do so, product team will still investigate this issue as well. Skip to main content. This browser is no longer supported. Save Save. Winr2 supports version of TLS 1. It appears that text-to-speech TLS does not support Winr2 server!
