Hi All. I am currently migrating from solr 3.6 to solr 4.1. In 3.6 to check the status of solr master/slave replication I've been using url: http://${SOLRMASTER}:${SOLRPORT}/solr/admin/replication/index.jsp from script. After migration to 4.1 this url is no longer available. Can you tell which url can be used from script to check replication status? Best regards, Rafal.

Hi all. I am currently thinking about monitoring a network link (bandwidth, latency, packet drop). I have a centos server which is connected to providers network through a switch. How to test the link? Should I: - use ICMP to ping gateway and collect staistics of time/packet loss/etc. - use software like here: http://www.cyberciti.biz/faq/linux-unix-windows-monitor-outgoing-bandwidth-latency/ (client/server) ? Is there an option to monitor bandwidth, latency, packet drop without installing additional software on gateway or external host? Best regards,...

...t you m problem, and hope to some additional ideas. I'm running a simualtion that in each step uses quite an amount of memory (but not exceedingly) - just to give you an idea - I create a pseudo population (n=1000, m=3) run lme and lm model and multiply impute (M=5) and do the pooling and final staistics calculation. Each simulation has 1000 cycles. I repeat the simulation a number of times for a set of different initial conditions. If I run them in a batch, say 100 initial conditions, the whole procedure tends to run slower with each new additional condition. I must tell you that not much of infor...

Hi, The department of economics at our university (Budapest) is planning a course on numerical methods in economics. They are trying to decide which software to use for that, and I would like to advocate R. The other alternative is Matlab. I have found comparisons in terms of computational time for matrix algebra, but I don't think that is relevant: the bottleneck for economists is usually
