Hello!

You can change global server configuration parameter PollCountForStatusChange. This parameter determines how many consecutive interface or network service polls should fail before declaring interface or service down. Because node declared down when all it's interfaces and services are down, this should help.

Just ignore it. It's a part of unimplemented feature.

Hi!

UNICODE build of libnxlp currently is not supported. This library used by server and logwatch subagent, both of them not using UNICODE as well.

V smisle hosti, najdennie posle togo, kak set' bila vistavlena v unmanaged? Esli da, to tak zadumano - manage/unmanage eto razovie operacii, esli potom k unmanaged ob'ektu dobavljaetsja novij podob'ekt, to emu unmanage ne delaetsja. Mozno sdelat' takuju opciju konechno. Edinstvennij vopros, chto delat' v sluchae konflikta - naprimer nashli router, kotorij v dvuh setkah, odna managed, drugaja net - chto s takim hostom delat'?

Na dannij moment suschestvuet tol'ko vozmoznos' nastroit' neskol'ko NetXMS serverov i peresilat' mezdu nimi sobitija. Obschej centralizovannoj konfiguracii poka net - k kazdomu serveru pridetsja podkljuchatsja otdel'no. Eto obsuzdalos' zdes' (v konce est' instrukcija po nastrojke event forwarding): https://www.netxms.org/forum/index.php/topic,256.0.html

Integracija s Google Maps - horoshaja misl', zapisal v TODO

это так, мысль на будущее.
кстати.. чем больше смотрю на Шаблоны, тем больше они мне по поведению напоминают Политики. всё таки шаблоны себя несколько иначе должны вести, а тут- вполне такие настоящие Policy.

Pohoze, nachat' nado s opredelenija chto takoe shablon i chto takoe politika

It's a bug Is it critical? If it's really critical, I can make a patch for 0.2.24, if not - please wait for next release.

Hello!

Below are some possible reasons:
1. Lost database connection.
2. Heavily corrupted database, where some tables for collected data (like idata_1734) does not exist.
3. Clock shift on server - if clock shifted back, server occasionally may try to write collected data with already existing timestamp.

You can try to run failed query in SQL query analyzer - it should give more diagnostic output.

Идея хорошая. Мы собираемся переделывать PORTCHECK субагента, чтобы можно было проще добавлять новые сервисы, можно будет сразу добавить и предложенную проверку игровых серверов. Я буду обращаться за дополнительной информацией когда до этого дойдем.

Нельзя - в этом смысл шаблона. Можно вынести DCI Nr. 2 в отдельный шпблон и накладывать его только туда, где он нужен.

Why?

Design flaw I agree that connections from agent to server can be very useful in many situations, especially for hosts with dynamic addresses or behind NAT. It is in my long to-do list, because it requires significant changes on server side, but eventually this feature will be available.

Удалять нельзяб это будет именно удаление ноды вообще. Надо выбрать шаблон, right click -> Unbind, и выбрать ноду которую хотим вывести.

Hi!

There are description of how to use ServiceCheck.HTTP(): https://www.netxms.org/forum/index.php/topic,28.msg87.html#msg87

Hello!

Here are translation of mentioned post, should be enough to setup shared resource monitoring.

It's an example of cluster monitoring configuration.

Case:
We have two cluster nodes: NODE_A and NODE_B. Cluster itself is called CLUSTER. Both nodes have NetXMS agents installed. Nodes are connected to public network 192.168.1.0/24, node A has address 192.168.1.11, node B - 192.168.1.12. Also, both nodes has private network 10.0.0.0/8, node A has address 10.0.0.1, node B - 10.0.0.2. There are 3 resource groups:
1. Cluster group, name: ClusterGroup, virtual IP 192.168.1.10
2. Shared disk, name SharedDisk, virtual IP 192.168.1.20. On active node seen as drive X:
3. Exchange server group, name: Exchange, virtual IP 192.168.1.30. On active node run Exchange services and drive E: contains shared Exchange data.


Requirement:
Monitoring service availability and disk space.


Configuration steps:

1. Create object of type "Cluster", call it CLUSTER (it is no necessary to match AD cluster object name)
2. In CLUSTER object properties add cluster interconnect network 10.0.0.0/8
3. In CLUSTER object properties on "Resources" page define resources (name - IP pairs):
    ClusterGroup 192.168.1.10
    SharedDisk 192.168.1.20
    Exchange 192.168.1.30
4. Now we can create nodes A and B. They should be created under CLUSTER object. As Ip addresses for new nodes should be used their fixed IP addressesd (192.168.1.11 and 192.168.1.12 in our example).
5. Check configuration of new nodes - virtual addresses of cluster resources should not appear as interfaces. If you select CLUSTER object in object browser, on "Cluster" page should be displayed correct position and status of cluster resources.
6. Now DCIs for cluster resources can be defined. Select "Data Collection" for CLUSTER object, and create DCIs as usual, except one: you should select correct cluster resource in "Associate with cluster resource" field. Fo example, for monitoring disk space on shared disk X:, you should set "Associate with cluster resource" to "SharedDisk" in our example. DCIs configured that way will be collected only from node which is current owner of associated resource.
7. All other configuration for cluster nodes can be done as usual.


There are also some predefined events related to cluster monitoring:

SYS_CLUSTER_DOWN
SYS_CLUSTER_UP
SYS_CLUSTER_RESOURCE_DOWN
SYS_CLUSTER_RESOURCE_UP
SYS_CLUSTER_RESOURCE_MOVED

You can process them as usual in event processing policy.

Hello!

Looks like compiler tries to use incorrect _CONTEXT definition from WinNT.h. Such result can occur if you have _M_X64 defined instead of _M_IX86 when compiling StackWalker.cpp. Maybe you have 64bit version of cl.exe first in your path?
