| - | ===== Even on an unconnected server, the fastdpi_1gb process by top showed a load of around 140% (on a 4-core CPU). Is it supposed to be like that?Now at about 50Mbit, top shows 160-220% CPU Load. Is this correct or is there something else that needs to be fixed? ===== | ||
| - | The high load at standby mode is due to the fact that the cards are not interrupted, | ||

| - | ===== How can I see the list of changes before installing? ===== | ||
| - | On the wiki front page we publish announcements of new versions and a list of changes, or you can install the yum-plugin-changelog package and use the changelog command <code bash>yum install yum-plugin-changelog | ||
| - | yum changelog 4 fastdpi</ | ||

| - | ===== Does the software only work with CentOS? We mainly use FreeBSD on our servers, is there a version for this OS? ===== | ||
| - | There is no version for **freebsd**. Now we support only: **ОС CentOS 6.4** or **6.5**, **ОС CentOS 8** (CentOS x86_64);\\ | ||
| - | We strongly recommend using the OS image specified [[en: | ||

| - | ===== Can I use a third-party monitoring solution? ===== | ||
| - | You can use SMNP monitoring solutions such as the zabbix agent. [[en: | ||
| - | |||
| - | ===== How is the load distributed across processor cores (12 cores/2 clusters)? ===== | ||
| - | The cores are functionally distributed between different dpi tasks so that they do not interfere with each other.\\ | ||
| - | 2 and 7 are responsible for traffic transit and are currently underutilized since there is not much traffic.\\ | ||
| - | You can check the distribution of functions with the command: | ||
| - | < | ||
| - | |||
| - | ===== Why are there processor cores unloaded (the 12th core is not busy)? ===== | ||
| - | The dpi has service functions: netflow generation, clickstream, | ||
| - | Their load is uneven and they can briefly load the core to 100%, so they have a separate core, so they do not interfere with the same transit. | ||
| - | |||
| - | ===== Why can one core be 100% loaded at typical DPI load? I can't get into the server, only rebooting helps. ===== | ||
| - | It is most likely the fault of kipme process, ipmi server remote control interface, maybe FW is not protecking against external attacks. When the process loads 100% kernel (any kernel) softRAID stops working, so it's not possible to log in to the server. There is also an article on other possible causes of problems with ipmi:\\ | ||

| - | ===== Are the utilities url2dic and ip2bin available in source, or for FreeBSD 9 x64? ===== | ||
| - | The utilities are not available in source and there are no plans to make them available in source. Freebsd allows you to run native [[http:// | ||
