Show slab usage in memory meter #151
Conversation

Note that free has recently been fixed to not include SUnreclaim in the slab cache. |

@OmegaPhil, so an ideal PR would be a version of this using SReclaimable instead of Slab? |
|
Basically. There is one outstanding thing I'm not yet fully aware of - conky is also treating Shmem as allocated memory that isn't counted currently - do you know how this works? I did some digging on the conky ticket but its an open question for me. free doesn't specially deal with shmem but then it was completely wrong until recently too. |
No, sorry. I haven't kept up with these things lately and each program seems to calculate things differently nowadays, so I'm keen on taking the community's advice. Thank you for looking it up! |

OK. For reference, at this instant on this machine thats been up ~2d: Shmem: 331352 kB Not taking into account SReclaimable is a much bigger problem than the ~324MB Shmem here (although if it is wrong, 324MB wrong is still pretty bad) - I'd recommend making the SReclaimable change now, and if I get a response (or find something out) via conky I'll feed back to you later. |

@OmegaPhil, ok! Will do. I posted a comment on shmem in the other issue. |
|
Cheers, sorry I've been stuck on a problem in one of my projects for hours - should be back on this tomorrow. |

It seems to be solved in #313 |
Slab is a kind of kernel memory which includes reclaimable usage. So it should be shown in different color.

Why I think slab usage should be separated is:
freecommand from procps doesn't includes slab usage in "used" (actually shown as cache == page cache + slab). (commit)Many thanks :)
