Hi Pramod, You can do this in the dashboard app itself (see screenshot).

Hi Miao, Hope this helps: Let us know if you have other questions. The following course might be of interest: DataMiner Automation - DataMiner Dojo

Hi Ashwini, My advice for this case would be to follow the following steps: Install DM and DB software if applicable with the same versions as you had when the backups were made for one site. If your...

Hi Luis, To prevent that DataMiner is using the wrong NIC for the wrong IP you can specify the order in the DataMiner.xml as indicated in the DataMiner Help through the NetworkAdapters tag. We encountered...

Hi Carlos, Indeed at the moment it is only possible to install DataMiner Cube for a specific user (not system wide). You can install DataMiner Cube from the following link: https://dataminer.services/install/DataMinerCube.exe...

Hi Laszlo, Reaper can be installed in different ways. If security is a concern, then there is only one viable option to install Reaper in side-car mode. In short this is to avoid exposing JMX to the network....

Hi Hugo, As you are doing an installation on Ubuntu I would recommend doing the installation from the deb package instead of from the source code. To install from a deb package you can run: $ sudo dpkg...

Hi Brecht, Logger tables are stored in a separate table in the DB created specifically for that element. So it should not be stored in the elementdata table in DB as it is already in a custom table in...

Hi Brecht, By default, the Primary key column, the display key column (which could be multiple columns) will be saved to the elementdata table in Cassandra. The reason why these columns are saved by default,...

Hi Hugo, From DataMiner version 10.2.3 it is possible to use AMIAC as Cassandra storage.

Hi Jens, You can find that information in the DataMiner help: Moving the Cassandra database to a different Disk

Hi Christine, Deleting the .mdmp files and the .hprof files should not give you any problems. These are created when a crash or heap error is encountered.

Hi Srikanth, There could be a couple of reasons why you see this behavior. In most cases it is related with a lack of resources (e.g. Disk, CPU, memory, network, ...). Can you evaluate if one of your...

All ssTables (the DB data on disk) is stored on the separate drive. When Cassandra does compaction it tries to clean up and group ssTables for more efficient lookup. To do this it needs to go over the...

Hi Paul, From your 'nodetool status' message you can see that the first node (from which you are probably running the 'nodetool status' cmd) is having a status ?N and this means the node is not started...

Hi Philip, You can rely on the information events to understand more about what actions/sets were triggered at the moment of the event. Based on your input I would assume that you have a vdx page in...

Hi Miguel, There should be no problem running Cassandra 4.1 with DataMiner. I don't have any visibility of what Cassandra versions are deployed in the field, but we did not yet receive any feedback on...

Hi Miguel, There are different ways to validate that the Cassandra Cluster is still running fine. The main goal would be to use the Apache Cassandra Cluster Monitor connector. This connector makes use...

Hi Hugo, If you are allowed to change this for your user you will be able to find this as following:

Hi Arunkrishna, If you want to be fully redundant (on DataMiner and DB level) you will need at least the following architecture (more info on Supported System Data Storage Architectures - DataMiner Dojo):...

Hi Alasdair, For general server monitoring, the Linux Platform Connector can be used. When you want to have more details on the Cassandra service itself (e.g. which nodes are up) you can use the Apache...

Hi Bruno, When a Failover switch is triggered, it will go through 4 steps: Stop the DataMiner software Release the VIP IP (or the first steps are covered by the server going offline abruptly) The other...

Hi Jochen, At the moment Cassandra Cluster is not yet released. However it is not the plan to support a mixed configuration with the initial release. The goal is to have one Cassandra Cluster for your...

There is a list available with registered product at AMWA (product owners of NMOS). So in general there are not that many (at least registered) that use the NMOS at the moment, however it is gaining popularity...

Hi Rene, For Cassandra there are two important ways of communication between nodes: Internode communications (gossip) This is needed to provide information between nodes on the Cassandra cluster in...

Hi Carys, Can you share with us for which connector you encountered this? It looks like you have some corrupted data in the database for table 4000. I would recommend making our techsupport@skyline.be...

Hi Philip, There are probably multiple ways, but an easy way would be to have two DNS records (e.g. 'first.mydomain.com' and 'second.mydomain.com') pointing to both the same IP. In IIS on the DMA, you...

Hi Shawn, I believe the time needed to gracefully close the services might depend on the load on your systems and the HW you are using. I don't have statistics on all systems. In general, most systems...

Hi, Found the trick. You need to add the following at the beginning of your automation script: engine.FindInteractiveClient("message test", 5, "user:"+engine.UserLoginName, AutomationScriptAttachOptions.AttachImmediately);...

You can make use of the Skyline.DataMiner.Core.DataMinerSystem.Automation (for automation scripts) or make use of the Skyline.DataMiner.Core.DataMinerSystem.Protocol (from protocols) NuGet libraries....

Hi Bruno, 1 - Yes they created more keyspaces for the tables, this is to have more freedom to configure what replication strategy/factor you want to apply for every set of data. We did get complaints...

Hi Peter, The information can be found in our docs: https://docs.dataminer.services/user-guide/Basic_Functionality/Visio/reference/Placeholders_for_variables_in_shape_data_values.html#paramdmaidelementidparameteridtablerow...

Hi Arie-Jan, Can you have a look through the webinterface if there are some settings in the device that could block the serial communication? Most devices have a setting to enable remote control or something...

Hi David, For the Cassandra certificate issues: You can play around with the encryption settings on the 'General' page of the connector. You can disable the TLS validation altogether or you can also disable...

Hi Ram, Not sure if a Failover is the best answer for you atm. If you want to have the ability to be fully operational when your main site is completely lost (also the equipment on the main site). Would...

Hi Jeff, There should be no problem restarting MySQL while DM is running. When the local DB goes offline, DM will go into offload mode. This means all data that needs to be forwarded to the DB will be...

Hi Dang-Khoa, There are multiple ways of doing this. Direct access This could be through port forwarding or by a proxy server of port 80 or 433 (see docs for more info on ports). It is advised to ensure...

Hi Arun, The setting is saved in the "C:\Skyline DataMiner\MaintenanceSettings.xml" file under BackupSettings. You can try to adjust it in the file and restart DataMiner. Just not 100% sure if the limit...

Hi Alberto, You can find the configuration file of all agents in your local appdata (%localappdata%\Skyline\DataMiner\DataMinerCube\CubeLauncherConfig.json). You can change the file or copy it to other...

Hi Bruno, For DB applications (e.g. Cassandra or Elastic) disk speed is important as it can be the bottleneck for the throughput of your DB. In our DataMiner Compute Requirements - DataMiner Dojo, you...

Hi Wale, It is possible to have a one node Cassandra Cluster, so the minimum would be one. Keep in mind that this means that you have a single point of failure (if that one node is down or does not respond,...

Hi Luiz, The Cassandra folder contains more than only the ssTables. Most likely you have some snapshots that are still present in your Cassandra folder. Can you have a look inside one of the table folders...

Hi Wale, It is already possible to enable encryption between your Cassandra nodes (Cassandra should use then port 7001 instead of 7000 by default). The configuration can be found for this in the yaml file...

Hi Ryan, Probably you will find entries in the log files of Cassandra mentioning that it was not able to delete the snapshots. E.g. WARN [RMI TCP Connection(298)-127.0.0.1] 2019-04-23 20:01:33,328 SnapshotDeletingTask.java:43...

Hi Ryan, The current backup/restore mechanism in DataMiner takes indeed the system tables from Cassandra. Which means that the setup is also included in the backup files. As a consequence Cassandra is...

There are two options in DataMiner for the Cassandra DB: Cassandra (Cassandra Cluster for every DMA or Failover pair) By default Cassandra is installed on the server where DataMiner is hosted, if this...

Hi Toh, We advise that you use the latest LTS (long term support) version. Currently this is 22.04 (Releases - Ubuntu Wiki).

Hi Jeremy, You could use low-code apps for this. It is very similar to dashboards, but it also gives you the ability to create multiple pages and buttons that can trigger (interactive) automation scripts....

Hi Luis, It is maybe a workaround, but it might unblock you while you wait for it to be tackled by SW. You can use a button in low-code apps to set your filter somewhere in DM for your user. To give you...

Hi Laszlo, If you are using the IP addresses everywhere and not hostnames, then there should be no problem changing the hostname of the server. I would still recommend if you are doing these types of...

Hi Bart, I have seen this problem a lot as well and would recommend raising a ticket for this. Most of the time this is encountered with SRM solutions (Export element could not find DVE child element...

Hi Syed, If you want to know what actions a user performed, you should use the information events of the DataMiner system or you can go to System Center => Users/Groups where you can select the user...

Hi Matthijs, AFAIK, there is no option to tweak the defaults ATM, but once the tables are created you can tweak the RF on your datacenters in Cassandra. You can also make use of the Apache Cassandra Cluster...

Hi Jens, The recommendation is to stay below 200MB for performance reasons. If you have a powerful server and lots of memory, you might be less concerned about going over it. In your case, you have at...

Hi Gelber, If you want to create custom actions or overwrite certain actions, you can create a wrapper for the SRM_ReservationAction script. You can configure then your script (wrapper) in the booking...

Hi Chris, Would it not be easier to use "not" in front of your expression? Extended conditional shape manipulation actions | DataMiner Docs This would allow you to use ^ST-BT$ (for equal) or ^.*ST-BT.*$...

Hi Bruno, The general rule of thumb is to create all your Cassandra nodes in one datacenter and point all your DataMiner agents to that datacenter. This mainly to keep the latency between the Cassandra...

Hi Joerg, We would recommend SSD. You can let Cassandra know (cassandra.yaml) if you are using spinning disks or SSD, this will improve how Cassandra writes to disk, but SSD will give you better performance....

Hi Alberto, Please find the default alarm colors in our docs: Changing the default alarm colors | DataMiner Docs You'll see that from the 9.6.4 feature release (10.0 main release) some default colors...

Hi Geovanny, We had two major improvements on another project in which we did subscriptions from many to many. It is depending on your use case if these will also help your case. Some improvements to...

Hi Naveen, All of the above are related to virtualization layers. If the virtualization layer is working flawlessly, it should not really make a difference for the services (they will not be aware that...

Hi Bernard, All current DataMiner versions support running Cassandra and/or Elastic database on (external) Linux machines. There is a minimum version from which Elastic can be used. From 9.5.0 it is possible...

Hi Jack, I would suggest having a look at this video: Services - DataMiner Dojo In short, you should be able to add the parameter in your service through editing the service (or service template)....

Hi Luís, As you indicated, the current backup tool can't move the created snapshots to a different server. An internal task was created to cover this request. There are already some temporary tools...

Hi Jeroen, DataMiner (once running) will continue to work when DB is unreachable. At that moment, DataMiner will go into offload mode and store all the information for DB into files. During that time...

Hi Sam, DataMiner 9.5 is a version that is no longer supported by Skyline. So no new fixes or versions will get released on that version. To see what versions are supported you can have a look on DataMiner...

Hi Jaime, There could be several reasons why you have this problem. The ones that we see generally in the field: Windows is not able to provide page files fast enough to Cassandra (could be because...

Hi Alex, As far as I know this is not a possibility at the moment. What you can do is create a correlation rule that triggers if an element is created on those DMAs. This correlation rule could notify...

Hi Jeyaram, The polling interval for real-time trending depends on your driver/protocol. In your protocol there will be some timers defined and in most cases this will be linked with the polling intervals...

Hi Gerwin, It is possible to do this through an automation script (see example code). Note: This example is making use of SLNet calls and we can't make any commitment that these calls will still work...

Hi Rene, You could use a regex replace feature in Visio. [regexreplace:x,y,z] with x the regular expression, y the input and z the string that will replace each match.  So if 1234.5678.9ABC or 12:34:56:78:9A:BC...

Hi David, Can you evaluate your settings on your machine?

You can run DataMiner on a VM that is hosted in Azure (or AWS). Keep in mind that this can be rather expensive if you want to have dedicated drive, low network latency, minimum specs, ...

Hi Min, When right-clicking on the DMS in the cube launcher you can select with what version of Cube you want to connect (see screenshot). I believe selecting 'Version provided by server' will do the...

Hi Richard, From our documentation, you need to follow the 'Failover DMA in a DMS' or 'DMA in a DMS using a Cassandra cluster' steps. The last one is if you are using Cassandra Cluster (one Cassandra...

Hi Philip, There are probably two options: Create an 'automation script' and compile it as a library (as from the documentation). Then you can use this 'automation script' as a library in your other...

Hi Richard, Benchmarking virtual environments can be quite tricky. For example, benchmarking one VM could give you excellent results while benchmarking all the VMs at the same time could give you poor...

Hi Min, Yes, it is possible to add another location in the data_file_directories in the YAML file. This means that ssTables will be divided over both those directories. If you ever want to return back...

Hi Ashwini, You are probably looking to do joins with GQI. If you are not familiar with this you can have a look at the following course (joins from 9:20): Queries - DataMiner Dojo This is part of a...

Hi Jason, The easiest is to look into the notices in your alarm console. If you have alarm trees that exceed 100 entries you should have notices with the following value: "Alarm history exceeded 100 alarms....
