NeDi Help

System Service

## Introduction

View processes and resources of your NeDi host and start or stop certain services.

## Usage

Click on to stop or start the given service.

This only works, if the services don't need to open any priviledged ports (< 1024). Of course you could run the webserver as root, but that can create security risks! Therefore NeDi's Syslog (syslog.pl) and snmptrapd run on high-ports and usually are redirected by an internal firewall.

## Details

- Top part shows and controls NeDi related services.
- Lower part shows all running processes and some system stats.

### Threads

Depending on the size and topology of your network, it makes sense to run several discoveries at the same time. Do this by dividing the network in a few sections using borders and different seedfiles. Then adapt your crontab accordingly.

At the end of a run the nodes table needs to be locked during calculation, with that no other thread meddles with them. Furthermore should Top RRDs only be taken care of by the last thread to finish or they're gonna look like Picassoes.

On the far right you see the discovery status (# of threads is revealed by hovering over . If the nodes table is locked a is shown next to it. In case a discovery terminated unexpectedly or a nodelock hangs, you can reset it by clicking on .
