Low Disk Sapace , File Reader is Down and Packet Capture is Down

Hello,

Somebody knows for what is used the next Filesystem:

Filesystem                                                      Size  Used Avail Use% Mounted on

/dev/mapper/vg_dlplamonitor-lv_root   50G   47G  3.1M 100% /

This because i have three codes error: Low Disk Space 1014, File Reader is Down 1008 and Packet Capture is down 1008. Besides on Servers Status one the two monitors installed is Running Selected while thw another one is Running

REgards,
