Linux is not configured with all-inclusive logging. If you need that you have to specifically enable it. See process accounting, syslog, audit service, iptables, other traffic accounting tools and the per-daemon configuration files. Couple of questions remain:
- How do you know it's 146 GB?
- What services are publicly accessible?
- What software do your sites run?
- Do your system and daemon logs show "odd" requests or errors?
- Is there anything else noteworthy?

- It is an Virtuozzo Linux based VPS we are monitoring it using Parallels Virtual Automation.
- Publicly accessible services are HTTP , FTP , MySQL.
- Some websites are build in PHP ,HTML,CGI and some website are using WordPress and zoomla.

That traffic is of only on that day now the traffic is normal.

- How do you know it's 146 GB? From Parallels Virtual Automation or what else?
- Do your system and daemon logs show "odd" requests or errors?
- Anything else noteworthy?

- PVA shows traffic of each VPS in Web Control Panel.

How do I check system and daemon logs "odd" requests or errors ?

Run them through Logwatch? (Also see this and this.)
