With iotop -o command I can see the write and read speed of the disk per second. But it varies a lot, from 0 to high values. I'd like to see an average of it per minute or per 10 seconds.



How can I do it?






linux iotop

  • sudo iotop -od 10 and sudo iotop -od 60 will show averages of 10 s and 1 min.

I hope sar is the better way to get the average result



 sar -d 1 10 | awk '/Average/ print $2" "$4*0.000512"MB/s "$5*0.000512"MB/s"' | sed 's#DEV.*#DEV rd_sec/s wr_sec/s#' | column -t


  • rd_sec/s and wr_sec/s are number of sectors read and write from the device. The size of a sector is 512 bytes.


  • multiply by .000512 to convert into MB/sec

Postfix configuration issue with fips on centos 7; mailgun relay

Image
Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
