@tursiops said in PortCheck vs NetSvc (user-agent): Yes. I've done that for some DCIs, e.g. created DCIs on a disk enclosures that itself could not be monitored directly, then set the source node to the server the enclosure is connected to. That way I can easily see which disks are in which enclosure (the instance discovery filter script I'm using checks for the enclosure id for this purpose). Cheers Hello Tursiops, Although with this solution I cannot use the response time calculation (as per my understanding is not available in the NetSvc subagent), your suggestion solved my problem for the reachability of the https endpoint and that's great for the moment  Thanks a lot. Regards, Marco

Hello! I'm using LOGWATCH subagent to monitor events from Windows event log. In many occasions happened that a node got crazy and I received 20K+ mails informing about a repetitive event happened every second (especially during the night). Since NetXMS doesn't provide an "in-house" mechanism to prevent this, thanks to Victor's suggestions, I found the following solutions that I'm reporting here to simplify life of users that had similar problems. Basic concepts is this: Setup a counter to increase every time I receive an event I'm interested in Send standard email if the counter is below specific threshold Send warning email when the counter is equal to specific threshold Stop sending email when counter is above threshold without losing the received events Reset the counter after a specific time frame since the first event Example, threshold 50, time frame 1h. This means that the system will send up to 50 emails in 1 hour, then after the 50th events (whithin 1 hour) will send an e-mail informing about the storm and will store events in the system without sending more emails. After 1 hour since the first event the counter will be reset (through a scheduled task)) and NetXMS will start again sending email for new events of that type. Here attached you can find my sample scripts to use as base for further developments. Scripts are partially parametrized, feel free to extend and post here improvements AlarmCounterTools: script for checking threshold of counter, increase counters and other support tools ResetAlarmCounter: script for scheduled task to reset the counter after specified time frame (I don't know ho to pass parameter "eventCount" and use directly function from AlarmCounterTools) IncreaseAlarmCounter: script to increase the counter (I don't know ho to pass parameter "eventCount" and use directly function from AlarmCounterTools) Scheduled task sample EPP sample (3 rules) AlarmCounterTools.txt ResetAlarmCounter.txt IncreaseAlarmCounter.txt [image: ScheduledTask.PNG] [image: EPP.PNG]

Hi Victor, Is the behavior of logwatch changed in version 2.1 when agent sends parameters to the server? As per my test seems that a new parameter is added at the end of the list (up to ver 2.0.8 I had 10 params sent and now I have 11, in my specific sample the new parameter added has value of '1'). Regards, Marco

@tomaskir said in Agent authentication: You can encrypt the cleartext key in Agent, or on Server, thats OK. Or you can only encrypt the key on one side, thats also OK. Yes, this is what I found myself with the three different tests, and this is why I said that from the documentation I wasn't able to understand that you can have all the combination, since for the clear text on the agent side there is the field SharedSecret   Regards, Marco

Hi, I've managed to install reporting server to run in Windows environment on MSSQL Server 2016 and AzureSQL. If I try to execute the default report "Alarm Resolution Timer" what I get is this error in the report server log (attached to the post there is the complete log): 20:30:30.089 [quartzScheduler_Worker-1] ERROR o.h.id.enhanced.TableStructure - could not read a hi value com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'hibernate_sequence'. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:216) ~[sqljdbc4-4.0.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerStatement.getNextResult(SQLServerStatement.java:1515) ~[sqljdbc4-4.0.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.doExecutePreparedStatement(SQLServerPreparedStatement.java:404) ~[sqljdbc4-4.0.jar:na] The only similar error I found is this: https://www.netxms.org/forum/installation/reporting-server-4315/msg20119/#msg20119 But no useful hints... Any other suggestions on how to solve? Regards, Marco reportserverlog.txt

Hi Victor, Thank you very much. I will be happy to be a beta tester! Regards, Marco

Use that keys: /VERYSILENT /SUPPRESSMSGBOXES /SERVER={IP or Name} /SUBAGENT=FILEMGR /SUBAGENT=PING /SUBAGENT=LOGWATCH /SUBAGENT=PORTCHECK /SUBAGENT=wineventsync /SUBAGENT=WINPERF /SUBAGENT=WMI /SUBAGENT=ECS /SUBAGENT=netsvc /SUBAGENT=ups

@victor said in Y-axis on line chart (dahboard): Hi, it cannot be solved without change in code. Please register issue in bug tracker to make Y axis always started at 0 configurable option for line charts. Best regards, Victor Hi Victor, registered as new feature request: https://dev.raden.solutions/issues/1402 Thank you very much for your support. Regards, Marco

@jmp_3f8h said in EVENT LOG SUBSCRIBE FAILED: @victor said in EVENT LOG SUBSCRIBE FAILED: Hi, there is no way to determine exact cause without access to agent log. In agent log you will find record started with text "LogWatch: Unable to open event log". Btw, if you can edit agent's config from console, you can enable file manager subagent and download agent's log file. Best regards, Victor Unfortunately no access even for the config file (agent is configured to reply only to "Servers"), I'll ask for a copy of the log file to analyze it. Thank you. Regards, Marco Problem solved, just for future reference: it is a virtual machine with automatic deployment, the specific Event Log monitored (custom) was not yet created when the agent started. Just changed the post deployment step to create the custom Event Log before starting the agent. Regards, Marco

Hi, yes, default auth method changed from PAP (the only one supported before) to CHAP. You can change it back by setting server configuration parameter RADIUSAuthMethod to value PAP. Best regards, Victor

Hi, currently agent send traps only to servers listen as master servers - which is probably wrong. I cannot remember what was behind this decision. I can change it in next release. Best regards, Victor

Hi, agent will re-resolve server name once per hour. Best regards, Victor

SMTP Authentication was added in 4.3, please see updated documentation: https://www.netxms.org/documentation/adminguide/event-processing.html#notification-channels

It works fine! Thank you very much! Marco

Hi, I choose to show last value in object overview for DCI with {instance} parameter, it works properly but sometimes it appears also the "generic" version of the DCI and not only the instances, see attached images (OK.PNG is as it should be and KO.PNG is the wrong one). Am I doing something wrong? Regards, Marco [image: ok.PNG] [image: ko.PNG]

@victor said in Portech MV-370 gateway to send SMS through proxy (in different zone): Also, if you know any web-based SMS sending service with REST API - driver for it can be implemented very quickly - it will definitely be easier then adding proxy connection support for Portech driver. Best regards, Victor Hi Victor, thank you for your help. I will try to explore your suggestions. Best regards, Marco

Hi, should be fixed in 2.0-M4. Best regards, Victor

@victor said in POLL ERROR: Request timed out: Hi! Looks like this node do not support SNMP (or it is blocked by firewall) and SNMP checking just takes too long. You can disable SNMP for this node if it is not needed. In fact, poll itself should be finishing anyway - it is UI timeout waiting for poller update messages. Best regards, Victor Hi! It's not a firewall problem, SNMP is not enabled on that virtual machine, so disabling SNMP poll solved the problem. thank you. Best regards, Marco

@victor said in Missing agents parameters: Hi, did you do configuration poll on that node? We didn't do anything to parameter selection in 1.2.17... Best regards, Victor Hi! Thank you very much, that was the problem! Best regards, Marco

@technak said in Communication session broken: could you send me download link ? I can see only 1.2.14 here. There is an intermediate -not official- release at this link: https://www.netxms.org/download/1.2.15-M1/ Best regards, Marco
