System Requirements

refer to the following system requirements for running litmus edge minimum requirements a litmus edge instance is designed to collect, analyze, and forward data these data operations could require heavy computing resources to be able to facilitate all the day to day processes a litmus edge instance will execute although it is possible to run litmus edge on a wide range of devices, not having enough computing resources for your particular scenario could create serious performance issues consider the following factors when deciding upon the hardware that your litmus edge will use what is the amount of data that will be processed? what is your hardware budget? how many devices will you connect to litmus edge? how many flows/analytics/applications/integrations will you need? what programming language and frameworks will you use? will you need frequent litmus edge manager litmus edge interactions (for example, in the case of automatic backups) as well? to address some of these questions, we recommend you first install litmus edge on a test virtual machine (vm) then, run a partial execution of all your possible workloads to see how it performs from there, you can get a better idea whether you need less, about the same, or a multiplying factor of your test vm's computing resources see below for setting up this vm recommended configurations a litmus edge instance is typically customized under one of the following three configurations data pass through reading and passing data executed externally exclusively on integrations minimal data processing and/or storage performed on the litmus edge instance most computing resources consumed by only devicehub and data storage/forwarding to integrations in stream processing low volume in stream processing of data using flows and/or analytics (for example, value change or anomaly detection) data stored in influxdb for local visualization using a container running the grafana or python application computing resources consumed by influxdb, flows, analytics, containers, and devicehub heavy in stream processing and application usage high volume in stream processing of all collected data involving complex flows and analytics multiple flows are configured with the maximum allowed ram in analytics, many groups operate, each including multiple processors several containers may be run for further data processing, traceability, downtime recording, and so on influxdb will require additional cpu and ram resources if a large number of devices and tags are configured each device will become its own influxdb data table (measurement) computing resources consumed by user defined code within flows, applications, and analytics flows the following table summarizes parameters for the above three starting configurations when sizing a litmus edge instance 127,175,166,187 false true unhandled content type left unhandled content type left unhandled content type left unhandled content type unhandled

litmus edge's traffic must open specific ports for certain plc devices to connect to litmus edge to manage firewall rules in litmus edge, see manage firewall rules docid\ p7splidisui2hj4mhdtpm ports for industrial systems and sensors connections are plc specific and should be open on a case by case basis see the industrial systems connection guide docid 8o4ksduafz6jcegj0whs4 for more information marketplace ports marketplace applications manage their own ports those ports are application specific and are outside of the iptables firewall other ports any other ports are blocked by the iptables firewall this means that the litmus edge flows application can initiate only outgoing traffic and cannot listen to incoming connections
