Checkmk Werk 12738: Skip empty values on bulk host import via CSV file

by Ronny Bruska

ID: 12738 Title: Skip empty values on bulk host import via CSV file Component: Multisite Level: 1 Class: Bug fix Version: 2.1.0i1 If values were missing for some hosts and this kind of value was selected in preview, e.g. "IPv4 address", importing was not possible because of a validation error. Such values are now skipped. The affected hosts are now imported without the missing value.

Checkmk Werk 12500: Call parse function even for empty data

by Moritz Kiemer

ID: 12500 Title: Call parse function even for empty data Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 This change only affect users with own SNMP section plugins developed against the *new* API. Previously the parse function of an SNMP section (or SNMP check plugin) has only been called if at least *some* data could be fetched from the host (the SNMP device). In the old API (Checkmk version < 2.0) this behaviour could be changed by setting the 'handle_empty_info' key - only then would the parse function be called for empty data. The new API will *allways* call the parse function, if the sections raw data is present in the fetched data (even if it is empty). It is the programmers responsibility to deal with an potentially empty data set. This allows for a subtle distiction: If the parse function returns `None`, no further processing is done, it is regarded as 'not present'. An empty return value could represent some valid information, such as an empty list of error messages. Note that this behaviour is consistent with the TCP data sources' sections, where we also may encounter sections that are present, but empty.

Checkmk Werk 12501: apc_inrow_system_events, liebert_system_events, printer_alerts: Services were not discovered

by Moritz Kiemer

ID: 12501 Title: apc_inrow_system_events,liebert_system_events,printer_alerts: Services were not discovered Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The services of the check plugins <tt>apc_inrow_system_events</tt>, <tt>liebert_system_events</tt> and <tt>printer_alerts</tt> could not be discovered if no events or alerts were present (i.e. almost never). This is fixed.

Checkmk Werk 12502: Rare bug during parsing for clustered custom plugins

by Moritz Kiemer

ID: 12502 Title: Rare bug during parsing for clustered custom plugins Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 This werk only affects users that have certain custom plugins developed against the old check API in a clustered setup. Specificly: This affects you, if you have <ul> <li>a custom check plugin</li> <li>using the *_item_state features in the parse function</li> <li>in a clustered service setup</li> </ul> In this case, you probably observed crashes of the parse function or stale services (we have never observed this theoretical bug). This will be fixed. However: If this actually affected you, you should consider moving all item_state related logic into the check function (as this will be enforced by the new API).

Checkmk Werk 12692: k8s_replicas: proper check message when replicas data is not available

by Wontek Hong

ID: 12692 Title: k8s_replicas: proper check message when replicas data is not available Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 In some instances, the Kubernetes replicas information is either incomplete or not available. The unavailability is usually of short period. In the previous version, this led to failure of the check. This werk introduces a mechanism to handle this event. The check initially goes into a stale state before displaying a crit status if the data is unavailable for more than 10 minutes.
