Memcached graphs not available

[luffy]

Hello,

I have a problem with graphs memcached. I use Memcached template : http://dealnews.com/developers/cacti/me ... l#download

When i was created the graphs, i have only the graph " Memcached Cache Hits and Misses " which works half.

Poller result :
06/01/2011 04:56:40 PM - SPINE: Poller[0] Host[777] TH[1] DS[26043] SCRIPT: python /home/sites_web/cacti-0.8.7g/scripts/memcached.py DNS_Server -p 11212, output: total_items:885438 get_hits:2590362 uptime:9090260 evictions:0 cmd_get:3033223 time:1306940200 bytes:234148631 curr_connections:53 connection_structures:124 bytes_written:3229701101 limit_maxbytes:268435456 cmd_set:885438 curr_items:151977 rusage_user:61.04 get_misses:442861 rusage_system:104.05 bytes_read:1713650774 total_connections:384988

The requests are corretly but the data don't update in the graph.

In "Graph Management" -> "memcached Bytes Used", i can see :
ERROR: opening '/home/sites_web/cacti-0.8.7g/rra/server_26035.rrd': No such file or directory

I tried to create the rrd file but i have the following message :
ERROR: mmaping file '/home/sites_web/cacti-0.8.7g/rra/server_bytes_26035.rrd': Invalid argument

Have you an idea?

Thank you.

regards,

Greg

That's not related (at least not directly). The rrdtool error shown from above should cause more hints in that poller.log
R.
