This chapter provides descriptions for all Juniper Netscreen Firewall metric categories, and tables list and describe associated metrics for each category. The tables also provide user actions if any of the metrics for a particular category support user actions. Shaded rows represent key columns for a particular category.
Percentage of CPU utilization in the last five minutes. The default warning and critical threshold values for this metric are not set. You can set values for these thresholds based on the load on the firewall and your network conditions.
A large memory consumption causes the entire system to slow down. To analyze what is causing the problem, use the Solaris "top" system command and observe any firewall processes that appear to be consuming an excessive percentage of memory.
Amount of time in milliseconds to ping the firewall. The threshold values for this metric are set for low network load conditions. You can provide a higher value for the warning and critical thresholds based on the load on your network.
Number of failed sessions. The default warning and critical threshold values for this metric are not set. You can set values for these thresholds based on the load on the firewall and your network conditions.

The agent for Linux and Windows communicates outbound to the Azure Monitor service over TCP port 443. If the machine connects through a firewall or proxy server to communicate over the internet, review the following requirements to understand the network configuration required. If your IT security policies do not allow computers on the network to connect to the internet, set up a Log Analytics gateway and configure the agent to connect through the gateway to Azure Monitor. The agent can then receive configuration information and send data collected.
Internet censorship in the People's Republic of China (PRC) affects both publishing and viewing online material. Many controversial events are censored from news coverage, preventing many Chinese citizens from knowing about the actions of their government, and severely restricting freedom of the press. Such measures, including the complete blockage of various websites, inspired the policy's nickname, the "Great Firewall of China", which blocks websites. Methods used to block websites and pages include DNS spoofing, blocking access to IP addresses, analyzing and filtering URLs, packet inspection, and resetting connections.
According to a Harvard study, at least 18,000 websites were blocked from within mainland China in 2002, including 12 out of the Top 100 Global Websites. The Chinese-sponsored news agency, Xinhua, stated that censorship targets only "superstitious, pornographic, violence-related, gambling, and other harmful information." This appears questionable, as the e-mail provider Gmail is blocked, and it cannot be said to fall into any of these categories. On the other hand, websites centered on the following political topics are often censored: Falun Gong, police brutality, the 1989 Tiananmen Square protests and massacre, freedom of speech, democracy, the Tibetan independence movement, and the Tuidang movement. Foreign media websites are occasionally blocked. As of 2014, The New York Times, the BBC, and Bloomberg News are blocked indefinitely.
According to Chinese studies expert Johan Lagerkvist, scholars Pierre Bourdieu and Michel de Certeau argue that this culture of satire is a weapon of resistance against authority. This is because criticism against authority often results in satirical parodies that "presupposes and confirms emancipation" of the supposedly oppressed people. Academic writer Linda Hutcheon argues that some people, however, may view satirical language that is used to criticise the government as "complicity", which can "reinforce rather than subvert conservative attitudes". Chinese experts Perry Link and Xiao Qiang, however, oppose this argument. They claim that when sarcastic terms develop into common vocabulary of netizens, these terms would lose their sarcastic characteristic. They then become normal terms that carry significant political meanings that oppose the government. Xiao believes that the netizens' freedom to spread information on the Internet has forced the government to listen to popular demands of netizens. For example, the Ministry of Information Technology's plan to preinstall mandatory censoring software called Green Dam Youth Escort on computers failed after popular online opposition against it in 2009, the year of the 20th anniversary of the protest.
Lagerkvist states that the Chinese government, however, does not see subtle criticisms on the Internet as real threats that carry significant political meanings and topple the government. He argues that real threats occur only when "laugh mobs" become "organised smart mobs" that directly challenge the government's power. At a TED conference, Michael Anti gives a similar reason for the government's lack of enforcement against these Internet memes. Anti suggests that the government sometimes allows limited windows of freedom of speech such as Internet memes. Anti explains that this is to guide and generate public opinions that favor the government and to criticize enemies of the party officials.
In February 2018, Xi Jinping appeared to set in motion a process to scrap term limits, allowing himself to become ruler for life. To suppress criticism, censors banned phrases such as "Disagree" (不同意), "Shameless" (不要脸), "Lifelong" (终身), "Animal Farm", and at one point briefly censored the letter 'N'. Li Datong, a former state newspaper editor, wrote a critical letter that was censored; some social media users evaded the censorship by posting an upside-down screenshot of the letter.
Foreign content providers such as Yahoo!, AOL, and Skype must abide by Chinese government wishes, including having internal content monitors, to be able to operate within mainland China. Also, per mainland Chinese laws, Microsoft began to censor the content of its blog service Windows Live Spaces, arguing that continuing to provide Internet services is more beneficial to the Chinese. Chinese journalist Michael Anti's blog on Windows Live Spaces was censored by Microsoft. In an April 2006 e-mail panel discussion Rebecca MacKinnon, who reported from China for nine years as a Beijing bureau chief for CNN, said: "... many bloggers said he [Anti] was a necessary sacrifice so that the majority of Chinese can continue to have an online space to express themselves as they choose. So the point is, compromises are being made at every level of society because nobody expects political freedom anyway."
Some media have suggested that China's Internet censorship of foreign websites may also be a means of forcing mainland Chinese users to rely on China's e-commerce industry, thus self-insulating their economy from the dominance of international corporations. On 7 November 2005 an alliance of investors and researchers representing 26 companies in the U.S., Europe and Australia with over US$21 billion in joint assets announced that they were urging businesses to protect freedom of expression and pledged to monitor technology companies that do business in countries violating human rights, such as China. On 21 December 2005 the UN, OSCE and OAS special mandates on freedom of expression called on Internet corporations to "work together ... to resist official attempts to control or restrict the use of the Internet." Google finally responded when attacked by hackers rumored to be hired by the Chinese government by threatening to pull out of China.
With the proliferation of Chinese social media platforms such as TikTok, WeChat, QQ, Weibo and Xiaohongshu (RED) abroad, concerns have been raised about data harvesting by Chinese technology firms since such companies are registered in the China and therefore fall under the jurisdiction of Chinese law, requiring access to data without warrant when requested by Chinese intelligence and public security authorities. Concern has also grown about the spread of Chinese language disinformation and propaganda on platforms targeted at overseas Chinese diaspora communities and the potential to sow discord and unrest towards host nation states and societies in addition to the exporting of Chinese censorship practices abroad, preventing the exercise of free speech by Chinese communities even when physically outside China. 2b1af7f3a8
