[2.4.0] Checkmk Werk 16511 created: Let cmcdump handle semicolons in plugin output

by Checkmk werks level 1

[//]: # (werk v2) # Let cmcdump handle semicolons in plugin output key | value ---------- | --- date | 2024-02-21T13:39:02+00:00 version | 2.4.0b1 class | fix edition | cee component | multisite level | 1 compatible | yes cmcdump would not handle semicolons correctly, leading to garbled or incomplete output and spurious errors. This has been fixed by escaping semicolons in cmcdump and unescaping them in livestatus.

This has now been fixed. The lines starting with `**ERROR**` will be ignored.

[2.4.0] Checkmk Werk 14223 created: Introduced topology visualization

by Checkmk werks level 1

[//]: # (werk v2) # Introduced topology visualization key | value ---------- | --- date | 2024-02-25T15:22:55+00:00 version | 2.4.0b1 class | feature edition | cee component | multisite level | 2 compatible | yes The topology visualization is a new feature that allows the visualization of complex interconnected networks. A simple example for this visualization is the parent/child topology. The new mechanism that comes with this werk allows the linking of external data with the data of the monitoring core. When it comes to the display, you simply define some starting points via the filter form. Based on these, the topology visualization then builds a mesh of incoming and outgoing connections. The type of external data might be * Netstat, showing connections between the interfaces/ips/ports * LLDP/CDP, showing the network neighbors There is a common data format specification for all external data. So you just can create your own data file which provides information about the relationships between hosts, services or generic objects which are not linked to the core. If you drop this file into a specific folder, the visualization will handle the rest. There is no need to write python code. Right now you can configure * Objects - either linked to an entity in the core or some standalone object * Icons/emblems which should be added to the object * Connections between objects * Line style/color of specific connections Since this is a quite visualization heavy topic and hard to explain only via text, feel free to check out the [thread](https://forum.checkmk.com/t/network-visualization-now-in-version-2-… in our checkmk forum We will also publish a blog article in the coming weeks ``` Important: The visualization only works if external data is provided in a special folder. At the moment these are not created by Checkmk, but come from external MKP developments. ```

[2.2.0] Checkmk Werk 14860 created: EC: improve handling of non-UTF-8 characters in messages

by Checkmk werks level 1

Title: EC: improve handling of non-UTF-8 characters in messages Class: fix Compatible: compat Component: ec Date: 1708674008 Edition: cee Level: 1 Version: 2.2.0p23 Previously, the Event Console would show an error such as "UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte" when trying to process a message that contained non-UTF-8 characters. With this werk, the EC no longer crashes. Any non-UTF-8 sequence of bytes is replaced with U+FFFD, the standard Unicode replacement character for an unrecognized character.

[2.4.0] Checkmk Werk 16170 created: snmp: Store OID cache per context group

by Checkmk werks level 1

[//]: # (werk v2) # snmp: Store OID cache per context group key | value ---------- | --- compatible | yes version | 2.4.0b1 date | 2024-02-07T09:54:40+00:00 level | 1 class | fix component | checks edition | cre SNMP caching didn't take contexts in consideration when storing OID data. This led to the same result being reported for the OID in different sections even if sections use different contexts. Now, SNMP caching stores fetched OID data for every group of contexts it was called with.

[2.1.0] Checkmk Werk 16506 created: aws: Inventorization of EC2 and ELB tags as host labels

by Checkmk werks level 1

Title: aws: Inventorization of EC2 and ELB tags as host labels Class: fix Compatible: compat Component: checks Date: 1708516567 Edition: cre Level: 1 Version: 2.1.0p40 There was a problem during service discovery which prevented Checkmk from assigning the AWS EC2 and ELB tags delivered by the AWS agent to their respective piggyback hosts. This werk fixes the discovery process such that the data is parsed properly and custom tags from AWS will now show up as host labels on the created piggyback hosts.

[2.2.0] Checkmk Werk 16404 deleted: omd cp: Fix etc/ssl/agents/legacy_ca.pem Points to Source of Copy

by Checkmk werks level 1

Werk 16404 was deleted. The following Werk is no longer relevant. Title: omd cp: Fix etc/ssl/agents/legacy_ca.pem Points to Source of Copy Class: fix Compatible: compat Component: omd Date: 1707904094 Edition: cre Level: 1 Version: 2.2.0p23 Since Checkmk 2.2.0 there is a agent CA located in <code>etc/ssl/agents/</code>. This CA is different from the site CA. In particular, if updating from 2.1.0 to 2.2.0, Checkmk will create a symlink <code>etc/ssl/agents/legacy_ca.pem</code>, which points to <code>etc/ssl/ca.pem</code>. After performing an <code>omd cp</code>. This symlink would still point to the site, which was the source of the copy. The symlink is now relative. If the site was created with version 2.2.0 or above no symlink is needed.
