I have two core switches - 4506E, and i noticed there are frequent cpu spikes on both of the cores switches. As its spikes intermitendly i couldnt able to anlyze the issue. I need inputs on the following,
1) Is there any Free CPU process monitoring tools to identify which process is spiking ?
2) Troubleshooting techniques to identify the issue.
I'm setting up a Network Monitoring System in Nagios and Nagvis. Now, I want to monitor the cpu and memory of the switches SGE2000 and SGE2010 with SNMP. Does the OID for the switches SGE2000 and SGE2010 (CPU and Memory).I can't not seem to find them on the Internet(searched for hours).
I have a medium enviroment with 2 x Cat4500 switches and 50 x Cat3650 plus few Cat3750 switches. I'm looking for a network mapping tool to map all the network equipment so I can easy to manage or trouble shoot the network. It doesn't matter if it's free or paid but something I can try first before buy.
I have been in this field for a few years and I found this book, Network Performance Toolkit: Using Open Source Testing Tools, to be very useful. It is full of great open source testing tools and has easy to use instructions for them all.However, to be more specific, I am looking for a packet generator that can simulate network packets over an extended amount of time. So the end result is I have this generator test my physical network for an hour but it simulates a week of real network traffic. Any tool, ideally it be open source?
I would like a free tool that would moniter the internet usage of our network. it has about 20 computers and would like the following features: be able to show the usage of each computer the type of usage, ie, browsing, downloading, streaming a total usage Is there such a free program? would Microsoft Network Monitor 3.4 be able to do the trick if i learnt how to use it?
I'm running Windows 7 Pro. I noticed tonight when I clicked on Network in Windows Explorer that in addition to my home PCs there is a PC with someone's name on it. My suspicion is that my wireless ISP has screwed up in some way. I ran SoftPerfect's Network Scanner and don't see any strange IP addresses, so this stranger's PC is not on my subnet. What tools are available to scan my network and give me more info about the stranger's PC?
I want to setup BB to monitor snmptraps with failure. The BB log shows can't connect to all switch ports 161, and I even can't telnet to XXX_17f 161 for example. My switches are Cisco C3550, C2950, ASA etc.
Mon Nov 7 15:43:03 2011 bbnet Can't connect to server XXX_17f on port 161 Mon Nov 7 15:43:03 2011 bbnet Can't connect to server XXX_9f on port 161 Mon Nov 7 15:43:03 2011 bbnet Can't connect to server XXX on port 161
I've just gotten a SG200-08 (SLM2008T-EU), which I would like to monitor remotely from Cacti using SNMP. It seems however, that this switch has no SNMP support - is this correct? Does this mean that there is no way to monitor traffic over the switch's ports short of making a script access the web UI?
Does the SGE2000 supports NetFlow? I've checked the Cisco docs and also called Cisco support to which no one has been able to answer me.
Anyhow, just in case it doesn't support NetFlow, how to be able to set up something that would be able to check the bandwidth usage on each port?
I've got a problem where I think the SGE2000 switch is failing when I pump around 190~200Mbps through x2 of the ports (Server A on port 1=130Mbps and Server B on port 2=60Mbps) of Multicast traffic (UDP). I can measure the output from the Streaming servers that provide the multicast content, thats how I know the input to the switch and I know that there are no packets lost or any errors departing from the servers, yet when I increase server B to say 80Mbps, I get break up and all sorts of problems on the client end STBs and it is happening on the multicast content provided by Server A too which is a different source, so I'm 99.9% sure its a SGE2000 switch problem which is why I'd like to monitor it somehow.
I had an interesting issue utilizing a monitoring software for our routers and switches. The monitoring tool indicated a few switches were down, however was unable to ping or telnet into them from the computer I had the software installed on.
Anu network monitoring software that would monitors constant network connectivity? I am working with a company who uses an Access database that checks members in and out of a gym. 6-8 people work in the database at any given time. Several times a day the users will get a network error and they have to force the database to close. Sometimes this happens to all of the users and sometimes to just certain ones. I believe the problem lies with the database (due to poor programming) but I want to monitor the network connectivity to see if and when the network connection is dropped and determine if that corresponds with when users begin seeing network errors in the database.
I live in a shared flat. And all 20 rooms are connected to this switch I believe. Is there any method to prevent the landlord/tech guy monitoring our internet activity (e.g. bandwidith activity, websites we looked at, etc.
I have a questions about protecting my network. My parent's have rented out my room, since I'm going to college, and I was wondering if there was a way to monitor the traffic that is going on in my network. Once the guy moved in, the wireless connection speed drastically decreased. I was barely able to sure the internet on my laptop. I currently have about 8 devices connected to my network. I am running a wired connection for my desktop so I don't feel any lag, but everything else runs on wifi.
I was wondering if there is a way to monitor the total bandwidth available at any given time? My ISP claims and is charging me for a certain amount of bandwidth but I suspect that during the day I am getting much less.
I would like to track available bandwidth continuously (or every 5, 10, 15 minutes) and log that data so I can show them the results. I'm on a Mac 10.7 but can use Windows XP also.
My ISP provide me with Thomson TG799vn (Gateway). The modem can be used with LAN cable and wifi function on it too.
The only computer that's directly connected to it is mine and I am currently using Ubuntu Oneiric and Windows 7. Is there anyway that I could monitor user (disconnect / ban any unwanted connection) connected to my modem.
From the gateway page I can see the below info but do not know how to use it :
user-0efb5820d0 Information Status:Active Type:Generic Device Connected To:WLAN (Wireless) Allowed on WLAN:Yes Addressing Physical Address:00:1a:13:b6:4d:ce IP Address Assignment:DHCP IP Address:192.168.1.70 Always use the same IP address:No DHCP Lease Time:0 days, 23:03:02
I have downloaded many software but it's useless because it provide me with none of the function I required.
I need to track and record all functionality, connectivity speeds and applications of a remote laptop. Here's the basic set up of my problem:We have 40 medical facilities in five Western States, each with up to 30+ pieces of hardware including thin clients, PCs, laptop computers and wall mounted touch screen kiosks operating on a variety of OS including primarily XP pro, then Linux and transitioning into Win 7.We have installed Aruba wireless network in each building on which our mobile medical cart laptops connect. Each facility has a different mix of primary and backup/failover ISP from DSL, Cable, T1 to Bonded T. All are at or exceed 22MB down, 5MB up save the T1s at their dedicated 1.5 and we monitor speeds and network stats trhough our gateway device. PfSense.All employees connect through an RDP (Remote Connection) to our hosting company in Atlanta, GA where the farm of about 28 servers reside hosting our medical, email and office applications.We regularly are contacted by nursing and clinical office staff complaining that "the network is slow". We review connection speeds, loads, ping times and confirm that there are no ISP Speed issues that are causing the "Slowness". However when we review exactly what the nurses mean by "slow" it invariably turns to how long it takes to log in to the RDP sessions and access then run their medical applications in the RDP. They often sit and wait for the RDP to load for five minutes or more and complain of waiting for their typing to catch up in the applications they work in.
We believe the slowness occurs once they are connected in the RDP and that their problems are occurring at the hosting company's facility, getting through their firewall, through profile management and server hardware/software but we can not prove this is the case because the hosting company always claims they see perfectly acceptable speeds and access on their side and we are locked out from access to monitor tehir environment. Changing hosting companies is probelmatic because they are specialised in our industry and leaving would be diffcult. I need some software that I can install on a few machines in a select few of our facilities that will track and record the actual user experience so that we can watch and review exactly what is happening, what the network stats look like and precisely where the user is experiencing "slowness".
I have an exhibition next saturday on network monitoring and I was given ftp server monitoring project. I'm only allowed to used linux based OS for this project. Right now I have 3 notebook. 1 as a client, 1 as a router and another 1 is for monitoring. Right now, I only can make a connection between the client and monitor notebook by using Freebsd in the router. How to setup a ftp server and how to monitor it?
As per me 24x7 network monitoring service is one of the best technique.Even we can protect large scale or enterprise level network with unwanted attacks or virus. Alternative better option of Network Monitoring Service
We currently have a 3/3 Etherloop. We dont have any internal IT as we are still small and while not a networking guy I can at least understand what is going on. Right now at peaks we are hitting 100% utilization.
We run a call center in house so I am trying to determine at the very least how much of this traffic is from voice data compared to everything else.Was running through our networking configuration and it just seems off to me. The following is the flow.
-Etherloop Demarcation > -Cisco Integrated Access Device > -D-Link DIR 655 Wireless Router > -24port HP Procurve switch > -24port HP Procruve switch >
Everything up to the first switch is a single line. The first switch has all ports running out except 1 which goes to the second switch. The second switch runs out to machines as well.
I am at the networking level where I understand a switch but have no idea what the IAD really does between the etherloop modem and the wireless router.
For some reason I feel like the router should not be setup in that manner and should be off of the switch. With the cisco IAD running directly to the first switch. So my 2 big questions are.
1. Does this setup even make sense.
2. Whats the easiest way to monitor traffic, at the very least it would be nice to see real time up/down and be able to log in. Then I guess using ports figure out what is being used by voice. My first guess was just putting a machine between the IAD and first switch and monitor and log the traffic.
1) How do you manage your inventory of network equipment from the time you receive a product into inventory to the time you decommission it?
2) How do you make aware the people who manage your network monitoring/reporting software that a device has been added/removed from the field?
2a) How do you notify the people who manage your network monitoring/reporting software of what is to be monitored on a new device in the field? Of a new interface that has been added/removed on an existing device?
2b) How quickly do you notify for 2/2a? i.e. minutes, hours, days, etc.
3) What types of interfaces and resources do you monitor on a network device?
I would like to make a monitoring system of my network based on Zabbix . I would like to use SNMP protocol with the Cisco RV180W but in that case, i need its MIB table to generate appropriate OID for CPU and memory using and network information. Where i can find this kind of information ?
