Hi all
what are the ways by which we can know and generate a report of the space remaining, memory(ram) used and the load on the server over a period of time. (1 Reply)
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)

Hello I am running a liferay application in tomcat on one of my hosted linux machine having 4GB of ram and 1 CPU.
I get the tomcat response really slow and with much digging I found that the cpu might be loaded and can be tracked with top command.
The following is the output of top command:... (0 Replies)
Currently have two ESP8266 modules testing some Blynk apps, whereI'm not so happy with the Blynk business model for developers, but that's another story.
So, with two of my ESP8266s currently "busy", I decided to work on the ESP32, and in particular the ESPWROOM32.

attach
ATTACH(5) File Formats Manual ATTACH(5)NAME
attach, session, nop - messages to initiate activity
SYNOPSIS
Tnop tag[2]
Rnop tag[2]
Tsession tag[2] chal[8]
Rsession tag[2] chal[8] authid[28] authdom[48]
Tattach tag[2] fid[2] uid[28] aname[28] ticket[72] auth[13]
Rattach tag[2] fid[2] qid[8] rauth[13]
DESCRIPTION
The nop request does nothing overt but may be used to synchronize the channel between two service hosts initially.
The session request is used to initialize a connection between a client and a server. All outstanding I/O on the connection is aborted.
The set of messages between session requests is called a session. The host's user name (authid) and its authentication domain (authdom)
identify the key to be used when authenticating to this host. The exchanged challenges (chal) are used in the authentication algorithm.
If authid is a null string no authentication is performed in this session.
The tag should be NOTAG (value 0xFFFF) for a nop or session message.
The attach message serves as a fresh introduction from a user on the client machine to a server. The message identifies the user (uid) and
may select the file tree to access (aname). The ticket and auth arguments contains authorization data derived from the exchanged chal-
lenges of the session message; see auth(6).
As a result of the attach transaction, the client will have a connection to the root directory of the desired file tree, represented by
fid. An error is returned if fid is already in use. The server's idea of the root of the file tree is represented by the returned qid.
ENTRY POINTS
An attach transaction will be generated for kernel devices (see intro(3)) when a system call evaluates a file name beginning with Pipe(2)
generates an attach on the kernel device pipe(3). The mount system call (see bind(2)) generates an attach messages to the remote file
server. When the kernel boots, an attach is made to the root device, root(3), and then an attach is made to the requested file server
machine.
