I add this dag in my CentOS-Base.repo,

name=Dag RPM Repository for Red Hat Enterprise Linux                            

when I install the rrdtool, I get error:

failure: repodata/repomd.xml from dag: [Errno 256] No more mirrors to try.
http://apt.sw.be/redhat/el7/en/x86_64/dag/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: apt.sw.be; Unknown error"

If this question can be reworded to fit the rules in the help center, please edit the question.

  • A bit of digging shows that most of RPMs from the DAG repository eventually moved to RepoForge, which was then declared 'dead' in 2016. There is a website for rrdtool, so maybe you can download the source and build it yourself. – Haxiel Jan 4 at 9:30
  • rrdtool is also part of CentOS7. – jsbillings Jan 6 at 2:04
  • thank you, finally I can install it directly in CentOS7. – 244boy Jan 6 at 4:19
