Hi,

please turn on agent crash dumps by adding to nxagentd.conf:

CreateCrashDumps = yes
DumpDirectory = some_path

and send crash dumps (if any) to [email protected]

Hi,

you have to add object access rights as well. They are assigned in object properties. You can also add your users to Admins group - it should have all object rights assignments already.

Hi,

you can use instance filter script to modify instance itself or just instance name. For example, if you instance is two numbers connected with dot you can use the following filter script:


instance = $1;
if ($1 ~= "[0-9]+\\.([0-9]+)")
{
   return %(true, instance, $1);
}
return true;


This script will keep instance as is (i.e. 4.2) but set instance name to second number (i.e. 2). You can then use {instance-name} in description to insert updated display name.

Hi,

alarms are grouped based on alarm key - if alarm with same key already exist when new alarm is generated new alarm will replace existing alarm and increase repeat count. Make sure you have meaningful alarm keys (or empty keys to disable alarm matching).

Hi,

this is short configuration instruction: https://wiki.netxms.org/wiki/How_to_configure_agent_to_server_connection

Yes, this is what zones are for. You can have overlapping IP addresses as long as they are in different zones.

P.S. You can also use Port, Login, and Password parameters in broker section.

Hi,

currently agent can connect to broker and pass published data to server as events or provide additional metrics with received data. You can connect multiple brokers to one agent. For each broker you should create section named MQTT/Broker/broker_name where you'll define broker hostname using Hostname parameter. Then you can use sections MQTT/Broker/broker_name/Events and MQTT/Broker/broker_name/Metrics to map receiving data to events and metrics.

Example MQTT subagent configuration:


SubAgent = mqtt.nsm

[MQTT/Brokers/Office]
Hostname = mqtt.office.radensolutions.com

[MQTT/Brokers/Office/Events]
MQTT_METERHUB_RAW_DATA = "cmnd/5C:CF:7F:25:79:D6/#"

[MQTT/Brokers/Office/Metrics]
MeterHub.Telemetry.RSSI = "tele/5C:CF:7F:25:79:D6/RSSI"
MeterHub.Telemetry.Time = "tele/5C:CF:7F:25:79:D6/TIME"


here agent will subscribe to one broker at address mqtt.office.radensolutions.com, will generate event MQTT_METERHUB_RAW_DATA for each message matching pattern cmnd/5C:CF:7F:25:79:D6/#, and provide two additional metrics MeterHub.Telemetry.RSSI and MeterHub.Telemetry.Time.

Hi,

as far as I can tell your schedule is not valid cron expression. As stated on web site "Generated expressions are based on Quartz cron format". NetXMS supports subset of UNIX cron format (see here for example: https://en.wikipedia.org/wiki/Cron#Modern_versions). It only supports *, /, -, L, and lists. Try to change your schedule to


30 23 * * 1-5

Hi,

you are using assignment operator (=) instead of equals operator (==). This script will work:



if ($1 == 1000000000)
return "1 Gbps";
if ($1 == 100000000)
return "100 Mbps";
if ($1 == 10000000)
return "10 Mbps";


Or you can simplify it a bit to


switch($1)
{
   case 1000000000: return "1 Gbps";
   case 100000000: return "100 Mbps";
   case 10000000: return "10 Mbps";
}

Добрый день!

А скрипт трансформации есть на DCI? Если да, то как он выглядит?

Попробуйте включить уровен дебага 6, дождаться появления дубликата, и прислать лог сервера (или найти в нем записи связанные с дублируючимися объектами).

Сервер выполняет такой SQL запрос для получения связанных событий по аларму:


SELECT event_id,event_code,event_name,severity,source_object_id,event_timestamp,message FROM alarm_events WHERE alarm_id=? ORDER BY event_timestamp DESC LIMIT 200;


и для каждого полученного события


SELECT e.event_id,e.event_code,c.event_name,e.event_severity,e.event_source,e.event_timestamp,e.event_message
FROM event_log e,event_cfg c WHERE e.root_event_id=? AND c.event_code=e.event_code;


можете попробовать выполнить такие запросы вручную и проверить насколько быстро они выполняются? И если медленно, то почему?

Hi,

starting with 2.1-M3 we have added integration with Grafana visualization tool. It is not PNG as you wanted, but still can be used to provide web UI for seeing graphs without actually giving access to NetXMS.

Hi,

currently screenshots defaulted to console session. We will add session selector in one of next versions.
