1. Linux tends to gobble up whatever memory thats not being used for buffers and cache, so on Linux boxes using nearly 100% of memory is normal. Use the "actual" reading to get the memory that is being used not including caching and buffers.
<br><br>2. is normal, Hobbit is very network intensive.<br><br>On the bb-test results, it looks like your DNS lookups are a little slow and your ping tests are taking a little longer than I would consider normal. I am running Hobbit on similar hardware as yours, monitoring over 600 hosts and have similar times for the DNS and ping.

All,<br><br>Have been taking a look at my hobbit server for the past week or so.<br>Wanted to ask a couple things.<br><br>The server is a DL360 G3 with two 3ghz processors and 2gb of RAM. It does only<br>hobbit and cricket (10 or so routers, so not a huge hit)
<br><br>I've noticed the following two things:<br><br>#1. I am constantly using 100% of my physical ram (no swap really)<br><br>Mem: 2075040k total, 2051928k used, 23112k free, 52172k buffers<br>Swap: 0k total, 0k used, 0k free, 1744168k cached
<br><br>is this normal? Not sure how to tell which process specifically is<br>eating up the most RAM.<br><br>#2. I am consistantly running with 2-300 ports in TIME_WAIT involving port 1984<br><br># netstat -an | grep TIME | grep 1984 | wc -l
<br>253<br><br>Im not sure if this is normal either, nor am I sure if it is bad or<br>not? Here is the output from some of the "bb" buttons at the top of my<br>hobbit page. If anything stands out, any help would be apprieciated.
<br>If I can provide any other info, let me know.<br><br>Thanks,<br>Jeff<br><br>bbtest-net version 4.2.0<br>SSL library : OpenSSL 0.9.7a Feb 19 2003<br>LDAP library: OpenLDAP 20213<br><br>Statistics:<br> Hosts total : 137
