# FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER
# DEALINGS IN THE SOFTWARE.
#
# Munin plugin for monitoring a multicore solr 4.* installation via mbean.
# It calls:
# > http://localhost:8080/solr/admin/cores?action=STATUS&wt=json
# and
# > http://localhost:8080/solr/corename/admin/mbeans?stats=true&wt=json
# for each core to retrieve cores and data. Verify those urls on your instance.
# Solr 4.* munin graph plugin
# Plugins configuration parameters:
#
# Configuration parameters:
# [solr_*]
# host_port <host:port>
# qpshandler_<handlerlabel> <handlerpath>
# availableram <ramsize in bytes>
# env.host_port <host:port>
# env.url <default /solr>
# env.qpshandler_<handlerlabel> <handlerpath>
#
# Example:
# host_port solrhost:8080
# qpshandler_select /select
# availableram 3221225472
# ex:
# env.host_port solrhost:8080
# env.url /solr
# env.qpshandler_select /select
#
# Defined checks:
# numdocs
# qps
# indexsize
# requesttimes
# documentcache
# fieldvaluecache
# filtercache
# queryresultcache
#
# Installation example:
# Install plugins:
# ln -s /usr/share/munin/plugins/solr_.py /etc/munin/plugins/solr_numdocs_core_1
# ln -s /usr/share/munin/plugins/solr_.py /etc/munin/plugins/solr_requesttimes_select
# ln -s /usr/share/munin/plugins/solr_.py /etc/munin/plugins/solr_qps_core_1_select
# ln -s /usr/share/munin/plugins/solr_.py /etc/munin/plugins/solr_core_1_select
