Vman Engine

[Tina Larzelere]

Upgradewas done successfully to 2023.4.1, and that error is gone, but when I try what was suggested by Solarwinds Support, either trying the "Download Installer" on the Polling Engine page, or trying the most current offline installer, either one just tells me Solarwinds is up to date and gives me no options to install an additional poller.

When I download the installer for the latest Orion Scalability Engine Installer, it start and looks like it may be exactly what I need, but then errors out saying the version isn't the one I need - which makes sense because the most recent version they have listed for that under the VMAN page on the customer portal is 2020.2.6, even though right above it, the main online and offline installers are version 2023.4.1.

A final note - our IT manager is under the impression that we can install the additional engines on the same machine (Windows Server 2019) we have the original engine and the Solarwinds Platform on - is that correct? Or is my issue that the additional engines need to be on separate servers this whole time?

The install is on the main polling engine. Go to yourserver/.../polling-engines-details and you will see a download installer link in the top right of the page.

You can increase the capacity of the additional polling engine up to four times, it's called a Stacked polling engine. The ability to do that is based on the license you give the polling engine, so coordinate with sales to get the right thing. I have the Hybrid Cloud Observability license, and all the additional engines are at 4x.

I already tried that - but just as a heads up, I called support and got someone different this time, and they confirmed that you cannot install the additional poller on the same server as the platform with the primary engine. A new server/VM is needed for additional engines. Just FYI for anyone in the future who runs into this.

FallbackPhysical descriptionEye colorBlackAppearancesCreated byVMan_2002Character IconsFallback is a character that appears exclusively within the VMan Engine. They appear whenever the engine fails to load a character, for example, when the character's .json file doesn't exist.

Fallback is a gray character with black eyes and a small mouth. Their head and limbs are separated from each other and holds a microphone in their left hand. When missing notes, their whole body turns blueish purple with a worried expression on his face.

I have not seen a true memory leak, but I did disable hardware polling in my environment because it kept using the memory on my APEs. I have moved all polling to my APEs to allow the poller to run the application more efficiently.

Sorry, read through that too fast. I overlooked the Recommendation part. I ended up disabling recommendations in my environment because I was also having problems with it. I have not tried yet since upgrading to 6.4.

We upgraded 1 week ago and so far this is our only real problem. The RecommendationService consistenly climbs to 9.5 GB fairly quickly after I restart it. I tried turning off Policies that had a lot of things in them, but I'm just considering turning off the entire feature if I can't figure this out...

The result of the case was that 8GB is the low side of the memory requirement for the recommendation engine in our environment. Our environment consists of about 120 ESXi hosts and around 1,200 servers. I find this memory utilization unacceptable. vROPS requires much less to do the same thing. I am about to put in another 32GB of RAM and we will see what happens.

I also upgraded to 12.1 and have a memory leak on SolarWinds Information Service V3. Total was running 8 - 9G but now runs up to the 15G total. I've had a ticket in to dev. but no resolution yet. I need to restart this service everyday or it will cause a problem to the entire system.

Your SolarWinds Platform installation consists of a main polling server (SolarWinds Platform Web Console and the main polling engine), and the SolarWinds Platform database server. The polling engine gathers device statistics and stores the information on the SolarWinds Platform database server. The main polling server reads the stored information from the SolarWinds Platform database server.

Your main polling engine polls a definite number of elements depending on the SolarWinds Platform product. Too many elements on a single polling engine can have a negative impact on your SolarWinds Platform server. When the maximum polling throughput on a single polling engine is reached, the polling intervals are automatically increased to handle the higher load. To keep default polling intervals, you need to add polling capacity.

"Scalability engine" is a general term that refers to any server that extends the monitoring capacity of your SolarWinds installation, such as Additional polling engines (APEs), Additional web servers (AWS), or High Availability (HA) backups.

Install an Additional polling engine. During the evaluation period, you will be able to see an APE evaluation license in the License Manager. After the evaluation period, no extra license will be displayed in the License Manager because it is included in your product license.

To deploy your SolarWinds Platform product in numerous remote locations without scaling up your installation, deploy a Remote Office Poller for Additional polling engine (ROP, mini-poller). Learn more

Centralized Deployment with APEs polls data locally in each region and the polled data is stored centrally on the database server in the primary region. All licenses are shared in a Centralized Deployment. Use this deployment if your organization requires centralized IT management and localized collection of monitoring data.

The latency (RTT) between each SolarWinds Platform Additional polling engine and the database server should be below 200 ms. Degradation may begin around 100 ms, depending on your utilization and the size of your deployment. In general, higher latency will impact larger deployments more than smaller deployments.

In a distributed deployment, each region is licensed independently, and data is polled and stored locally in each region. Scale each region independently by adding APEs. You can access monitoring data from each region in a central location with the Enterprise Operations Console (EOC).

If you specify any port other than 80, you must include that port in the URL used to access the SolarWinds Platform Web Console. For example, if you specify an IP address of 192.168.0.3 and port 8080, the URL used to access the web console is :8080.

SolarWinds Platform module traffic. Open the port to enable communication from all polling engines (both main or additional) to the Additional web server, and from the Additional web server to polling engines.

To deploy your SolarWinds Platform product in numerous, remote locations when you do not need to scale up your installation, use a Remote Office Poller for Additional polling engine (ROP, mini-poller).
