+# WeatherMap with LibreNMS
+Intergarting LibreNMS with Weathermap, allows you to build network maps to visulaize network traffic rates.

+
+### Installing WeatherMap
+
+### Step 1. 
+Extract to your LibreNMS plugins directory `html/plugins` so you should see something like `/opt/librenms/html/plugins/Weathermap/`
+The best way to do this is via git. Go to your install directory and then `html/plugins`.
+Enter:
+    `git clone https://github.com/librenms-plugins/Weathermap.git`
+### Step 2. 
+Make the configs directory writeable by your web server, either `chown apache:apache configs/` or `chmod 777 configs`.
+I'd highly advise you choose the first option, replace `apache:apache` with your web servers user and group.
+### Step 3. 
+Enable the plugin from the LibreNMS Plugins -> Plugin Admin menu.
+### Step 4. 
+Create your maps, please note when you create a MAP, please click Map Style, ensure Overlib is selected for HTML Style and click submit.
+### Step 5. 
+Also, ensure you set an output image filename and output HTML filename in Map Properties.
+I'd recommend you use the output folder as this is excluded from git updates (i.e enter output/mymap.png and output/mymap.html).
+### Step 6. 
+Enable the cron process by editing your current LibreNMS cron file (typically /etc/cron.d/librenms) and add the following:
+LibreNMS:
+    `*/5 * * * * root /opt/librenms/html/plugins/Weathermap/map-poller.php >> /dev/null 2>&1`
+### Step 7. 
+Now you should see Weathermap Overview -> Plugins -> Weathermap
+
+Optional: If your install is in another directory than standard, set `$basehref` within `map-poller.php`.
